Firefox 技術支援討論區

In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

You know how you can type a URL and then Ctr+Enter and FF autopopulates the .com? Well years ago "Shift+Enter" autopopulated ".net" and "Ctrl+Shift+Enter" autopopulated ".org".

I really liked that feature. I know a lot of people don't, or don't see its point; that's not important.

About three years ago, I added UserChrome.js and enable-UserChrome.js , which acomplished the two autopuopulating tasks quite nicely.

Until about four weeks ago. I don't know if an FF update stopped reading those two .js files, or if there's a conflict somewhere else, or what. I don't know where to begin - other than posting here for help.

Thanks in advance!

• UserChrome.js is in the subdirectory: C:\Users\[ME]\AppData\Roaming\Mozilla\Firefox\Profiles\gaydtewj.default-release-1
• enable-UserChrome.js is in C:\Program Files\Internet Shenanigans\Mozilla Firefox\defaults\pref (firefox.exe is in C:\Program Files\Internet Shenanigans\Mozilla Firefox )

Cut /copy and paste, nightmare!!!

what is going on? Cut / copy and paste should be easy, its not. Open a new tab, google homepage, and unable to paste the item I had just copied from another tab, it will only work when I go back to original and recopy? Too time consuming this issue.

I was set up, in myuserchrome.css, to hide my pinned tabs on the tab bar, allowing them to still be available in the "List all tabs" menu, see first image

.tabbrowser-tab[pinned="true"] { display: none !important;}

All of a sudden, it reverted back

That first image, with the hidden tabs, is actually from Librewolf, with has the identical setting.

Can I get an explanation for what this does

link text

Is it supposed to do something different than the windows taskbar mouse thumbnail

link text

I saw no difference when enabled.

I can't turn off lazy loading. I set the following about:config settings to "false":

browser.sessionstore.restore_on_demand browser.sessionstore.restore_tabs_lazily browser.sessionstore.restore_pinned_tabs_on_demand

Nothing changes. When I start Firefox, it simply won't load all tabs. How do I fix this?

using ver 117.0.1 on LinuxMint 21.2 all website and search engines work well, only can't use DuckDuckGo, get error message: "Firefox has detected that the server is redirecting the request for this address in a way that will never complete

Please help

Hail:

System Software: Win11Ent_x64 v22H2 (b: 22621.2283) MFF v18.5.0.0

No matter what I try, my MFF keeps crashing at startup. For some reason, it tries to open 2 pages the windows at the same time, which is illogical. I deleted firstly my: sessionstore.jsonlz4 logins.json to no avail.

Then I tried to open MFF through elevated CMD with the command: C:\Program Files\Mozilla Firefox\firefox.exe -safe-mode Again, 2 windows pop crashing immediately.

I do not understand why all of the sudden, it tries to open 2 different instances at once. This makes no sense. I am out of ideas, having tried many an option found on Google, but which none give me a solution.

If anyone has an idea, I would be quite darn thankful. This MSEdge crap that I need to use now is not quite my thing.

Thank you. Ke'Ylan

Many bugs and crashes with Firefox

1. 1 Not able to install an automatic update, via the Menu Help --> About Firefox (or Thunderbird). This bug / problems sits already inside the earlier versions of Firefox and Thunderbird.

• A No new version is shown.
• B Firefox (or Thunderbird) tries to download / install this update, bug become someway corrupted and also stuck in this process.
• C Firefox (or Thunderbird) says to apply the update you must restart the program. After Firefox (or Thunderbird) was restarted, the program keeps trying installing or downloading this same or another update. I see a spinning circle only, no progress bar. Waiting, trying again later or another restart from Firefox (or Thunderbird) does nothing.

Only way to update Firefox is via https://www.mozilla.org/en-US/firefox/all/#product-desktop-release Which always shows the wrong language. Only way to update Thunderbird is via https://www.thunderbird.net/en-US/thunderbird/all/#product-desktop-release Here, I can click on letter from my language and download the setup package. After this update installation was done, the Help --> About (program name) window show the program is last version. But not seems not always the last version, like version x.x.01 to x.x.02, then tries to install this newer small version and gets stuck in the same loop or corruption.

• D You must use the setup package, because the installer doesn't work, likes to abort the installation and shows error messages about something gone wrong. Installer package is incomplete or damaged, not for current version and Windows.
• E For last newer versions, they seems not working anymore directly. The program can be restarted once or few times before it seems working. Until other bugs appear.
• F Always adding a new and faulty shortcut, but I have already a working shortcut on my Desktop. Icon hasn't logo from Firefox or Thunderbird, but the setup icon.
• G Sometimes you cannot start Firefox or Thunderbird, due the update did something wrong.

Missing file(s) and/or some strange error message after I clicked on the shortcut from the program. Another run from this "update" setup is needed. Remove a or all "Firefox.exe" from the Taskmanager list.

• H Bug that stops add-ones working. This can be happen due the general function / thing for add-ones inside Firefox crashes, become bugged or corrupted. 1 add-one or more add-ones take the others and stop working, become bugged or corrupted. Add-ones will forget things, their work / functions or do it halfway. Has something to do with the installation and/or data from add-ones. They seems to not having support or do anything about their problems.

1. 2 Random many crashes without any useful (error) messages, can be with closing the program itself.

Already from earlier versions of Firefox. And also Thunderbird too. This bug seems to sit deep inside the programs. I should be to use Firefox, Thunderbird, Notepad together, with having a some folders open. Switching between them can be annoying slow. Takes longer time be before responding. I'm seeing empty white or black windows. Only last selected section is visible, has the text and smaller pictures. I can have Firefox and Thunderbird left open for hours and later finding one or both programs are closed by itself. No reason, no permission given to do that. Add a new tab or click on a current site, there is no (fast) respond. Same for buttons, filters and filling in forms on a site. One program can pull the other program in closing to when the one is crashing. Also Windows will show several error messages about programs are using to much memory and must be closed. If this has programs listed, then Firefox seems to appear most here of the programs I'm using.

Updating doesn't fix anything Using the safe mode and new profiles are no long time solutions, every time anything is gone or nog working better.

It seems you must have 2 profiles running at same time when you want read something and not switching back between every minute or so. If 1 is near crashing, you have still the other one running.

1. 3 Why I'm seeing 20x to 72x a Firefox.exe in my Taskmanager? They takes a lot of memory, showing different sizes. I started Firefox once. This is not needed.

1. 4 Some sites seems to not work in Firefox or takes longer time.

Same for responding on clicking, using filters, buttons and sending forms. Clicking on those (annoying) accept (popup) windows. Unable to login or confirm an (security) action like this with a word or number given via e-mail. Might be something for the site. When you need to use Private Browsing for this.

1. 5 Icons from installed add-ones don't appear in main bar, at right side. How to use them? Before they did.

1. 6 Site using third party host sites are slow and mostly don't work. Connection errors.

"Seems fine here, but something with you". Refresh page doesn't fix it. Wait and try again later, how long? Firefox should block these sites.

1. 7 After updating to Firefox version 115.0.2 and continue my last session, there are appear several new bugs.

• A I cannot longer visit sites. Even earlier visited sites don't load. Firefox keeps stuck in loading or receiving site info data. Sites don't appear, just an empty (white) page. Also about:support doesn't work. Strangely, I can visit Google.com but not open any site from there. I tried Private Browsing, so no add-one can do something with this.

I had Firefox running for some hours, these sites are still stuck in "loading" or something else.

• B Right click to open a site or page in a new tab doesn't longer work. Right click menu appears, but action will not be done. Which can be strange at top, missing or changed items.

• C Same to copy line of text or picture, action isn't longer "remembered".

Now, I created again a new profile and again this doesn't fix them. Even more bugs and stranger. Again lost everything, settings, sites, installing dictionaries and add-ones. Stupid.

• C1 I can visit websites, but with some strange things, not always working fine.

That makes it to post my problems here.

• C2 Cannot longer type keywords in the addressbar and after pressing Enter, you should visit Google with search results. Firefox thinks the given keyword is a not existing website.

In Settings (via about:preferences#search), there are no search engines (Google, Wikipedia, ect) in the list, who should be there by default. Also there's no default search engine selected, the list therefor is small and empty.

• C3 Yet visited near 10 sites, who I cannot visit any of the sites with my other long time using profile. Then Firefox crashed by random, white empty window. Windows adds not responding at end of the program's title bar. I could restart Firefox after that, get the "continue after a crash" tab and revisit any of these sites in their opened tabs.

• C4 A site keeps saying cookies are disabled / denied, while minimal are accepted when some of that stupid (popup) windows did show. This means: Some stupid messages don't disappear after clicking "OK", the "X" or close buttons / links. Site might not work fine or on some parts. Something can follow you browsing through the site. Not able to visit that site or part.

• C5 A site keeps saying there is an ad-blocker installed, but there is no add-one like that installed. This means: Stupid messages like these keep appearing; site cannot work fine; you cannot visit the site due some invisible wall or blocking thing. Some can follow you browsing through the site. This is very annoying.

• C6 With one profile I cannot longer open sites who worked before. Keeps loading, shows URL in addressbar and on the tab.

And the about: .... pages. While with a new profile I can visit those sites, but right click menu is bugged.

• Cannot open site or page in new tab. Only on Google based sites are working for unknown reasons, but not YouTube.
• Missing items or I can see more gray things and lines.
• Cannot copy selected text. Stil having old or wrong text.
• Cannot Search with Google, this option is missing.
• Cannot see the source code from the page, due action is not happen.
• On sites that are working you can only read that current content. Can open links in new tabs, but their pages are empty / white, keep loading forever.
• A few sites don't load and still giving a empty page. Loading takes longer then needed. For same site.
• Use Google by typing the keyword in the addressbar doesn't visit Google site, but Firefox thinks the site doesn't exist, is wrong typed. You must go to Google.com and typing the keyword in the textbox here.
• If a site worked first, then later it cannot working longer, keeps stuck in loading and showing a empty white page / tab.
• Login for some sites is not longer possible, email send with security word or number doesn't appear. I can send myself a test e-mail to this e-mail address. Waited the time enough and made a new attempt, still the same.

Windows PC. Firefox version 117.0 x64. Via Help --> About Firefox, because about:support doesn't show the version and build.

For some time now I have been having trouble with viewing you tube video's. At times the video freezes or just sort of locks up. But, I don't have the same problem with other browsers, Chrome, Brave. So, it just seems with Firefox this issue pertains. Can some one please help so I don't experience the Firefox you tube problems. Thank you.

upgraded to v118 9'30 Bookmarks lost and not able to access old profile, or restore using "Manage Bookmarks"

See attached: Only see one real profile (current, new) in App Support > Firefox > Profiles. The second profile that exists has virtually nothing in it compared to the new one created upon upgrade. Only three tiny files key4,cert9,pkcs11. Nothing else to restore from.

Bookmark manager >> restore >> despite seeing 10 dates to chose form , error messages every time, "unable to process the backup file." Now what?

I do see a "places.sqlite" file which seems to show "last modified" date of prior to my unfortunate update. But when I try to have Firefox open it, nothing happens. Just new browser windows every time.

THX in advance.

Over the last year I have uninstalled FF removed settings then reinstalled from scratch. Its been over a year now and FF never can pin point where I am at. Today it says I am 1300+ miles from where I am. I really don't want to go back to using Chrome but it appears I will have to as it normally has my exact position. I travel for 6 months of the year and have 3 internet connections shared via an internal WiFi that I use 99% of the time. They are connected via Starlink, GoogleFi (T-Mobile) and AT&T SIMs. I have a SSID with the _nomap suffix and that fixes Chrome but FF NEVER seems to know where I am, no matter how many times I clear the browsing data. I really don't want to go back to Chrome, but I cannot do my work if FF thinks I am somewhere else all the time. Geez, If only there was an addon or extension that would override FF location so I could tell it where I am. I'm in FF Hell. -Bill

So my last thread on this was archived without anyone giving me a reason or answering my question.

I have had issues with the website Archive of Our Own since last November, when I tried to change the site skin and permanently changed the default font of that site to something called Lucida Sans Unicode, when it's apparently meant to be Lucida Grande.

This much I was able to work out via my previous thread, but when I asked for that last bit of help, nobody answered and my thread was instead archived.

I don't know how to change a font on a specific website. I don't even know if the site has tools I could use that would work for me. All I know is I still cannot read bold or italics on Archive of Our Own with my screen-reader, NVDA, unless I use reader view, which excludes author's notes and comments, and I had thought I was close to a breakthrough before my thread was unceremoniously archived.

For reference, the thread is here: https://support.mozilla.org/en-US/questions/1403415

I tried inserting a link via the button above this box but it did not give me the necessary code used in this forum for links, so a straight url is the best I can do.

Since my last Firefox update, tabs crash or freeze and cannot be resolved. Each time, I have to shut down Firefox to open a tab. This makes shopping impossible as links to payments do not respond or say they are loading but never load. I have tried all the possible solutions and fixes mentioned on here but nothing is working. I have never had any trouble with Firefox before so this is a pain.

Hello,

On my firefox browser the Duo Security website keeps looping and not letting me login. I have tried private window and also have tried to install firefox again. The Duo security website is able to load on other browsers like Chrome and Edge without any issues. I also deleted the appdata and app profile and it is still not functioning. Any other recommendations that I can try?

Website is: https://api-263d2dfd.duosecurity.com/frame/frameless/v3/auth?sid=frameless-0e4e2d68-a138-4a07-8ad9-d7aae0f9fe5d&tx=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJkdW9fdW5hbWUiOiJzcGlrZXAiLCJzY29wZSI6Im9wZW5pZCIsInJlc3BvbnNlX3R5cGUiOiJjb2RlIiwicmVkaXJlY3RfdXJpIjoiaHR0cHM6XC9cL3NoaWJib2xldGguYXJpem9uYS5lZHVcL2lkcFwvcHJvZmlsZVwvQXV0aG5cL0R1b1wvMkZBXC9kdW8tY2FsbGJhY2siLCJzdGF0ZSI6IjVlMDNmOGM5OTcxM2MxZDdhYzRkNjlkMzZlYTAxYTU4LjY1MzM3MzMyIiwiZXhwIjoxNjk1OTU5NzU0LCJjbGllbnRfaWQiOiJESURLMkhSNEdGMTVJWUhMNEQ3VCJ9.wnLBrsdlaHjvudLT9w6rcD43QyQurgYR0UGIHYg2BXqP8TqNiFP5PN1C3l8jtYgA37LHrGbP6YvOYlY1MMOpYw

Thank you,

I have a General Motors account that I can't login to. https://www.gmccanada.ca/en/ownercenter/service They recently changed to multi authentication using Microsoft. I can login to the first step but after I enter the sent password in the second step nothing happens. I have tried basic some trouble shooting like Firefox trouble mode, clearing cache and adding web site to exceptions in settings. GM Help Line told me to use a different browser!!!

I have always used Firefox, but also have Chrome and Edge on my 17" PC. For the past week or so, my scroll bar (on right side of screen) has "disappeared". It is actually still there, but so skinny that it cannot be seen or used. I Googled solutions to this, and found an article that had 8 possible solutions. I went through all 8, went into the various control options. Still, the same problem. Downloaded the latest version of Firefox and installed. Still the same problem. So- I decided to see if it was an issue with my pc. I tried the Chrome browser. It works fine. I tried the Edge browser. It works fine. I know now that the problem is with the Firefox browser. Something "went wrong" in the latest version. To add to this -- I also have to note that if I shut down and restart the pc, I can get the Firefox scroll bar to return (sometimes). BUT (this is really weird): if the scroll bar appears normal, the bar at the top of the page (not sure what that is called) does not work correctly/ is missing features. This is what happens: there is no X to exit a page, there is no "V " sign to make a page small, etc. All 4 symbols that should be in the top right side of the top bar are missing. Also, there are no tabs available. It won't allow you to have more than one tab! So, if you are in your gmail (for example), you must close out the gmail in order to do a google search or do anything else! Something is terribly wrong with the latest Firefox update.

I really want to use firefox. I really do. But firefox's memory management is making that very difficult.

I have 8GB of RAM, which really ought to be enough, but inevitably, over time, firefox will munch and munch and munch until it has consumed all of it.

And then... my system crashes. I lose work. I get angry.

Well, okay, I use linux, so after this happened a few times I stuck firefox in a systemd scope and limit it to 90% of the memory of my system. At first, that didn't work because firefox would simply eat into the pagefile, until it had consumed all of it (or as much as I entitled it to), at which point firefox would desperately try to do.... something, very frantically, which would lock the CPU usage to 100%, again bringing down the system. So I limit its RAM and prohibit it from using the pagefile, and now, it's just firefox that dies.

....

But, really, that's still a problem. I still have emails partially written, forms filled out, work is still lost. Is it really so abhorrent to take out the trash that you'd rather just commit suicide instead? I say take out the trash, because firefox will restart, reload those very same tabs, and carry on with a fraction of the memory usage. Something's been dropped, and it wasn't important (well, other than the content of that email I've been composing for the last half hour).

So. If I'm going to continue using firefox, which I would very much like to do, there needs to be some way for it to gracefully say to the user: "I've run out of available memory. I'm going to have to..." (for example) 1. perform garbage collection (do whatever 'minimize memory use' seems to do... which is not much, but something that really ought to be the default action in this situation) 2. clear the buffer of some videos being played, or some cached results or something, i dunno. 3. gracefully stop loading the current tab, or process, or whatever, and say to the user "I've run out of resources to continue. Please choose one or more tabs to close in order to continue"

Then, at least, I can sacrifice my background music tab, or something else unimportant, to buy enough time to copy that email into notepad, submit that form, or just run 'minimize memory usage', and be able to carry on.

Watching videos on Twitter/X doesn't seem to work too well on Firefox. I don't have an account, but I sometimes have to watch a clip on the site. The problem is that you cannot skip the video i.e. you cannot move the dot that shows where you are on the video; you have to watch it from the start, till the end. You cannot also change the volume, apart from clicking on the "mute", so technically here you have the options of full sound and no sound. Twitter has always worked perfectly on the Microsoft Edge that came with the Windows on this desktop PC (bought in fall 2020).
