Firefox 技術支援討論區

This has happened a few times before after a Firefox update, but the most recent occurrence was after the update to version 117.0.1. My mouse wheel will not scroll in the bookmarks drop down menu, I have to use the up and down arrows in the drop down menu which is very slow. When the scroll wheel did work in the past, I could be scrolling and then move the cursor to the up or down arrows and scroll even faster still using the scroll wheel and get to the folder I want a lot quicker. The scroll wheel works normally while scrolling through webpages, the only place it doesn't scroll is the bookmarks drop down menu. I'm running Firefox version 117.0.1 (64 bit) on a Windows 10 notebook PC. Any help would be greatly appreciated, thank you.

Keep getting this on a number of websites. Most of them I have used for years. Can't give the websites as there are too many but some are pitchsidemanager.com, hattrick.org, skysports.com and sportinglife.com . Just four of at least 14 give the Hmm. We’re having trouble finding that site message. I use No Proxy and have my anti-virus turned off when I get the message. I have tried various other proxy settings but the same thing happens. The thing is that I have to keep refreshing the page until it does actually connect and that can take a good few minutes. Sometimes I have to restart the browser. Why is this happening since the last few updates?

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.

I got a notice that Firefox (and Thunderbird) were updated this morning. Took me an HOUR to find out how to make the miniscule font in my inbox larger. So.. suddenly, new problem.

When I click the Firefox icon to launch the browser, and reopen my tabs, It opens for a millisecond, then closes faster than I can try to read if there is an error. When I click it AGAIN, all my tabs are GONE and I have to search for them manually, which is a royal pain.

Why is this happening? How can I stop it from happening? This is annoying as hell.

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

Good morning. My Firefox version is 117.0 and I am running Windows 11 Home. Currently except for Ublock all my other addon icons are grayed out on my toolbar. My webadvisor, Capital One, just gray. This is a new behavior and I'm not sure what happened. I am also curious why just Ublock is colored in. Thanks in advance for any help you can give.

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 )

My Firefox browser automatically updated a few days ago. Since the update, the browser now crashes repeatedly during basic browsing, making Firefox essentially unusable. For instance, retrieving Yahoo mail, reading articles, accessing login pages -- the page will enter some type of refresh/reload cycle and crash the browser.

I opened the browser in troubleshoot mode and the problem did not occur. Following the Mozilla instructions, I disabled extensions and reopened the browser normally, and the crashes continued. I have not taken any additional actions.

This problem began immediately after the latest browser update on 9/13.

There was no such problem before, after the 117 update, the CSS theme I use is constantly reset and the browser returns to its default theme. The screen goes black for a moment and then the theme resets or the browser crashes. Is there anyone who has experienced the same problem? Any possible solutions?

Using this theme: https://github.com/Neikon/Fox11

I'll add 2 pictures of what my browser looks like when normal and crashed.

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

Under about:preferences#privacy choosing "Max Protection", choosing Max Protection, be it NextDNS or Cloudflare means my synced profile takes 30+ seconds to load/authenticate.

Windows 10 22H2 Pro on a domain.

On MacOS, near-zero delay.

Both go through same router.

This seems...wrong.

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

For the past month or so, every time I launch Firefox, it freezes exactly twice:

1. After 5-10 seconds of just being open, it will freeze and stop responding to input. Any animations, videos, blinking text cursors, etc. in the current webpage continue to play as if nothing is wrong. After a second or two of being frozen, it will return to working correctly.
2. I can use it for a few seconds and then it will do the same thing and then eventually turn white and say "(Not Responding)" in the title bar, but always immediately after a click or keyboard input happens. If I open a website and then continue working in other programs, it will not freeze until I refocus Firefox.

Once both freezes have happened, everything works as normal until I close all Firefox windows and then relaunch it later.

I provided the full troubleshooting information report below (apparently it's not public!), but in summary: Firefox version: 117.0 build 20230824132758 OS: Windows 11 version 22H2 build 22621.2215 GPU: Intel Arc A750, driver version 31.0.101.4644 (8/11/2023). I know it's is unusual, but I know someone with an Intel Arc A770, also running Windows 11, who does not have this problem with Firefox.

This does not happen on my laptop, which is also Windows 11, and Firefox Sync is working between them. I'm also using Firefox Sync with my Pixel 6 and iPhone X and neither of those has any issue.

I have already tried:

• Rebooting my PC
• Running Firefox in "Troubleshoot Mode":' no extensions enabled, same behavior
• Running Edge: no freezing issue, but I don't want to use Edge for so many reasons
• Reinstalling Firefox: I ran the Firefox uninstaller, deleted %AppData%\Mozilla\Firefox, and then reinstalled. It froze the same way immediately after launching the fresh install, before I signed in and synced all my data back.
• Running sfc /scannow: No problems found, freezing still happening

Are there any further troubleshooting step I can try, debug output I can enable/collect, etc.? This is really annoying and I'm all out of ideas.

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

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.

On a late model Dell laptop, there are no domains listed under Exceptions-Cookies and Site Data. When I key in a domain (whether using www., http, https, or just the domain name by itself.) and click on Allow, that website is not added. It's the same as if browser security is stuck on Remove All Websites. With the same Privacy and Security settings on my desktop, I do not have this problem, so it appears not to be a matter of altering particular settings. Short of removing and reloading Firefox on the laptop, which might work but not teach anybody anything, are there suggestions?

After the latest update (117.0 64-bit) I now do not see the '+' sign in the tab bar. I have 40 tabs open (please, no negativity - it's always worked for me), but if I close all of the tabs it reappears. Re-open the original 42 tabs and it's gone again. Close them and it reappears, etc. Now for the fun bit: starting from scratch with a new window - the '+' is there, but open 20 more tabs and it goes.

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.

On 30 August 2023, when opening Mozilla the second time in a day, a pop up window emerged asking whether I allow Mozilla to make changes on my hard drive (or: hardware - I cannot remember now) due to the updates.

I clicked yes, as otherwise Mozilla would not work, then an opening site appeared about the new features of the update, and talking about the possibility of the VPN service.

It seems that now I am working on the latest version of Mozilla released first on 29 August 2023 - 117.0. When checking in the settings, the date of the installation was also 29 August and not 30 August. This made me puzzled, why I got this pop out window only on 30th, and in addition only after the second usage of the browser (however, when checking in my comp settings, the update of Mozilla is dated 30 August 2023)... In addition, as never before I have seen Mozilla asking for making hard drive changes, I got worried whether it was not a kind of virus or other malware pretending to be Mozilla.

Could you please confirm whether the pop-out window asking for the changes to hard drive was indeed just Mozilla asking for valid changes? I am very worried I got a malware on my computer, although the antivirus scan does not show anything.

I have asked some friends and they had the actualization automatically done without this pop-out window.

I have checked some online discussions and verified in the properties that Mozilla is NOT allowed to run as administrator. Also, the "Run this program in compatibility mode for:" was also unchecked.

Thank you in advance for your answer!
