Firefox Support Forum

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.

It loaded and played OK prior to this update.... works mighty fine on another browser, if this is not fixed I'm through with Mozilla AND you can remove my account!

Looking in task manager-: Firefox.exe 45,24K Firefox.exe 3,16K Firefox.exe 27,484K Firefox.exe 7,392K Firefox.exe 7,344K Firefox.exe 15,735K Firefox.exe 7,320K Firefox.exe 169,932K, I round it off to about 250MB

Yes I cleared the cach, I change profiles..... as said by each update about:config gets bigger and bigger.

I used to like Firefox because it let me set my browser up in an intuitive and comfortable way, and it was able to easily do the things I wanted to do. Then simple and useful features (e.g., tabs under the address bar) were hidden in about:config. Then they were removed completely, and you had to use third-party extensions to restore them (e.g., getting the refresh button on the address bar). Then, the third-party extensions were blocked so that you had to copy and paste third-party code into userChrome.css (e.g., restoring "View Image").

I hate updating Firefox, because it gets worse every time. This browser has turned to absolute garbage, and it just keeps circling the drain. Wasn't Firefox supposed to be the customizable browser? Mozilla seems to have decided that customization needs to be completely wiped out, and features need to be removed for...some reason?

Why is this happening? I shouldn't have to be afraid of the update button, but it's become a "make Firefox even worse" button. My only consolation now is that Mozilla won't have any more major updates for my operating system, so I might be okay for a few months.

Hello FF community. I come here for a question, maybe a confirmation (I'm gonna try to be as short as possible ).

I'm using for years infamous Aris-t2 customCSS. I'm about to "jump" from FF v88 on my desktop to V115.0.3esr. I tested everything on my laptop, and set everything on the customCSS so it looks like my actual V88. It's almost identical, but one thing is bugging me: the scrollbar.

Scrollbar on FF115 isn't the same anymore than in V88 as you can see on the screenshot I posted (test scrbr for V115, scrbr2 for V88). The clean one with "3lines grab button" I actually use is less "eye catchy" than the new one. I've made some researches, and apparently, starting FF V97 about 2 years ago, scrollbar has been change to use W10 "flat like" one, and at FF106+, every older code was apparently removed. I tried to changed a few things in about:config, like "widget.non-native-theme.enabled" or multiple commands about scrollbar, nothing changed.

So I just wanted to know if someone could confirm me that the old scroll bar I use is now impossible to get back, or if there's a command I miss that could do the thing.

Thanks, have a nice day ^^

All my search results now use google, thanks to the FORCED installation of the search engine google. Even after I have deleted it and deleted it and deleted it and deleted it and deleted it, ALL SEARCH RESULTS ARE NOW FROM GOOGLE, whether I like it or not. Mozilla has FORCED A COMPLETELY BROKEN SEARCH ENGINE ON MY PC(google), and now i can't rid of it, AND THEY ABSOLUTELY REFUSE TO HELP ANYONE.

It astounds me that there is not a dedicated article on this subject. I did an internet search - 'Infinite Scrolling Complaints'. Usability Issues Caused by Infinite Scrolling =

Why is there zero zilcho nada discussion about this?!? Thank you, Mozilla Firefox, for your consideration.

Firefox worked fine until the latest update 115.3esr, at time it slows to a crawl... I am now sick and tired of Mozilla and Firefox, they are about to get the boot - my style, I've used them since about version 2.

Looking in the task manager Mozilla makes it look a disgrace, at time it's hard to get a fix on some entry's because they bounce up and down.

Firefox.exe 45,24K Firefox.exe 3,16K Firefox.exe 27,484K Firefox.exe 7,392K Firefox.exe 7,344K Firefox.exe 15,735K Firefox.exe 7,320K Firefox.exe 169,932K, I round it off to about 250MB

Does these look about right? Why can't they just have one .exe? (Win 7 Pro x64)

Thanks Dave

Hi. Is there a way to customize the order of Firefox headers and footers on printed pages (including print-to-pdf)?

I prefer the header to be url only, in the center. While the footer has page on left; title in the center, and date on the right.

This used to be easy to accomplish with print options in older versions, then -- as the print dialog changed (and actually improved a lot in most *other* ways) I had to turn to about:config modifications like those described in the 1/27/21 reply here: https://support.mozilla.org/en-US/questions/1323433. But now I can't seem to find any way to have any control over print headers besides "on" and "off."

One problem I find with having both page title and url on top is that these can be long, causing one or both to be truncated.

I'm using Firefox 115.3esr.

I use an IRS web site to pay taxes. I can not get in. It says I have to use a browser with TLS1.1 or 1.2. Dose firefox use this. If not how can I get it?

Thanks Galen Alldrin

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

Hello everyone,

to archieve some good old games, I use an special version of Firefox. Firefox (MyPal): 29.2.0, with Adobe Flash preinstalled, Disk-Cache

For most games it will suffice: After loading all content online, it will be available offline too. But... some audio/video files will be saved in memory cache - %temp%\mozilla-temp-files\*[random-auffix] - instead of in disk cache. After closing session they get deleted and after restart they are saved again, with another suffix.

Sample file: http://arcaneonlinegame.epizy.com/Arcane/frames_files/midi/Ophelia's Journal.mp3 that is shipped with http://arcaneonlinegame.epizy.com/Arcane/Arcane.htm

How can I tell Firefox to permanent save streamed audio/video files, like Firefox does with everything else? In the end the music should play if I open the browser offline too.

Thank you in advance for your help. Drago

hello, many years ago, I used to be able to keep my browser history for years. now it only saves about 1 year and 6 months. since it is my memory, I found it very helpful. I can't find any information on how to customize that feature so it is never deleted. I'm using firefox 115.2.1esr on windows 7. thanks a lot for your help.

I'm running 115.2.1esr x64 bit on Windows 7 pro. games on Facebook will not load I get 'Your browser does not support graphics API "WebGL2" error'.

In 'about:config' shows GL2 is enabled, yet Facebook games works with Google Chrome and MS Edge browsers, this seems to point to a Firefox issue.

I removed Firefox entirely, cleaning the registry etc, installed the latest version and get the same result.

Can anyone throw light on this? If need be I'll enclose

the troubleshooting info. 

Thanks, Dave

OS = Windows 7 Pro. Web-browser = Firefox. Both worked very well for many years on desktop PC and laptop. Recently desktop PC repeatedly reported "Windows Explorer has stopped" whenever Firefox was started. Today I updated Firefox on my laptop after several weeks of non-use. "Windows Explorer has stopped" appeared immediately Firefox started - error never seen before on the laptop. Could the most recent update to Firefox be the cause of this fault?

Lost power. Computer shut down. Reopened Firefox and no passwords. Looked in profile and there are 4 files logins.json.corrupt (149 kb) all created today at same time and 1 file logins.json (2 kb). I ASSUME my passwords are in the 149KB json file? If I delete logins.json (2kb) and rename one of the 149KB to logins.json, when I reopen firefox, it just does it again: renames logins.json to logins.json.corrupt (149kb) and creates a new logins.json (2kb). Is there anyway to recover these passwords? Windows 7 Latest version of firefox

Thanx

Deleting autofill entries does not work per article. The info is still there. Clearing history does not work either. Do I need to restart computer for it to forget/delete entries? Thank you. Fred couvrette
