Firefox Support Forum

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

The styles look astonishingly wrong, I really think it is a problem on my end, but cant figure out how to fix it, as you can see in the pictures, text is incorrectly sized and/or justified, color gradients are also weird looking, as well as sizing of many elements and tons of other things.

I have tried to completely remove Firefox from my system and reinstalling it, that did not seem to fix it. The reason I think is is a problem of mine is because i was playing with fonts (emojis weren't working on my system,not on Firefox tho, now they are in both)

I don't think the things i did with the fonts did anything to Firefox, since this problem only showed up on Firefox, but since the problem arrived just after a reboot while I was installing and removing the fonts, I think its important to mention.

To sum up I think the problem comes from my local configuration of Firefox, I probably did not delete it all before reinstalling, I am running (Arch btw) a current version of EndevourOS.

Hello! I think I have tried EVERYTHING to get Firefox to stop crashing in the past 6 months. Today I am so frustrtated. Can anyone point me in the right direct. (and yes this happens with a fresh install, disabled add-ons, safe mode, yadda yadda yadda

If you can help me...BLESS YOU!!!

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

An example of the problem: Firefox does not rnder the page https://www.ebay.co.uk/itm/164957094349?_trkparms=amclksrc%3DITM%26aid%3D1110013%26algo%3DHOMESPLICE.SIMRXI%26ao%3D1%26asc%3D238391%26meid%3D7ab2984ab89c490d9d19c64154175f61%26pid%3D101195%26rk%3D5%26rkt%3D24%26sd%3D402300560285%26itm%3D164957094349%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebNoToraCoCoViewsNoHighIdfOrSortByFinalScoreBlenderWithPromotedViewItems%26brand%3DUnbranded&_trksid=p2047675.c101195.m1851&amdata=cksum%3A1649570943497ab2984ab89c490d9d19c64154175f61%7Cenc%3AAQAGAAABQJxAynw2%252BiqzPDrRSEdA1OtGPHECjXiPIHTAGGaFXyfAhhOOcI0evIqLAV5dzxfkWlXm6ww1t0P09GMtcbSuFZjf5HidAoI3BLEE5q9IzcpZf1TZn1%252BLTOgqc1OD9sLjUiICuetx8VnxmROZ45L3noIgk65aQJuCoPA0d32OWfO52LE5XKsl22M11N9hzVfwHgluh%252F5HKiKhVl5Tsx0wb0b0dE30VWGeE6KisowiOj70Bzel9x4sBW7H8CN3vmNB2XZxJ3WwTx5I56fEAax5jK2zMEYDr0au%252Fk%252FCwLpDP%252BFvJPj2%252BRIxUzguSZgC5le17lkTY6CuGTF9xYRefAzw8ks%252FtcGsNkPKFb7ZfNXkOLe1k28NQbsvOuhPVcLk1pb3Joal6Ssw3egfQv4HF3D4vL6v6k1xWnbVepvH8lGXPENE%7Campid%3APL_CLK%7Cclp%3A2047675&epid=23034767275

properly. A lot of the text comes out in very narrow columns. The problem happens quite often on eBay. Chrome does render it properly. Could you please look into this? Thanks, Jon

My problem is this:

If I click on the open new tab button, and then I keep my cursor there, such that I get the little tooltip "Open a new tab (Ctrl+T)..." , Firefox will stop the address bar from updating---it won't show my keyboard inputs, not will it search, or do anything else. This will resolve itself after I move my cursor away from the open new tab button and the tooltip stops showing, even my inputs will appear there.

This quite annoying, especially when opening a tab to search for something quickly...

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Amazon 'Look Inside' pop-up does not work with FF as I've configured FF. Iv'e included a screen snip.

I've unchecked block pop-ups but still the 'Look Inside' doesn't work.

Hi.

Using Windows 10. Suddenly, Mozilla gives the "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window" message. I've tried all steps listed on the help site except reinstalling Windows 10, as the comment made said this would require reinstalling programs that did not come pre-installed on my PC, which I don't want to do if possible. I have uninstalled Mozilla, and the install stalls at about 70% with the aforementioned error message. Any help would be greatly appreciated! Thanks.

Hey folks, hopefully you can help with this mysterious issue!

I've been running Firefox successfully on my Windows 10 PC for a long while now. Last night, for some reason it simply ceased to work. New windows and tabs would not load any content. I also couldn't access the Settings at all (clicking on Settings in the browser menu produces no results or feedback.)

Yesterday, I had Firefox open all day (I usually have my computer on all day), and it was working fine. Around 8 or 9pm, I first noticed that none of my open tabs were loading any content, and the tabs had the "loading" animation playing. New tabs would also not load any content. I assumed it was an internet issue as I did see my internet connection get disrupted once or twice. I did not see anything (apps, etc) on my PC updating.

This morning I found Firefox was still not loading anything, although my internet connection was fine. I tried opening Chrome, and it ran just fine. Everything else that it is internet or cloud based on my PC is running fine too. So it seems to be an issue just with Firefox.

I have listed my steps to troubleshoot below, but I want to note one weird thing I observed: Even when Firefox is closed, and Task Manager doesn't show any Firefox processes open, my PC seems to think Firefox is running. For ex. while trying to uninstall Firefox or delete certain files, I would get a warning to "close Firefox first" or "can't perform this action while app is running." After seeing these, I would again confirm that Firefox appears closed and Task Manager shows no related tasks.

My PC build: - Windows 10 Home, 64 bit - Version 20H2 at start of issue (updated to 21H2 during troubleshooting) - OS build: 19044.1526

Things I have tried for troubleshooting already: - I have WebRoot on my computer due to my job, and I asked our IT staff if they could see WebRoot blocking anything related to Firefox on their end. They said it was not. - Used "Firefox Refresh" - Uninstalled and reinstalled Firefox - Cleared app cache / app data - Updated Windows from 20H2 to 21H2

Note: This message was sent on a different computer & browser

Hello,

Before the release of Firefox 99, the drag and drop function of e-mail using OWA (Microsoft Outlook) stopped working. In the last version of 99, it started working again (and I was very happy). My browser just updated to 100 and it stopped working again (and, of course, Firefox recommends not downgrading).

This is getting very frustrating, as I use Firefox at work and it is actually a lot of time wasted, going in and attaching files without drag and drop. I am on the verge of abandoning Firefox as my browser, since these features work in both Safari and Chrome. However, I do like the usability and security of Firefox, so I am hoping you can fix this very soon.

-Chris

After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

Not sure when it began, probably before the current version, i.e. it's not related to the latest update. When exiting, everything seems fine at first but then Crash Reporter pops up. If I try to restart my Windows/PC with FF open, the restarting becomes blocked by Firefox, so I have to cancel the restart and deal with Crash Reporter first.

The same crash happens in Troubleshoot Mode.

I don't have any special security software (aside from Malwarebytes with real-time protection disabled).

Latest reports: bp-3e00592e-2756-43bf-9642-01b550220502 bp-2435de7c-8279-4d85-b151-b94380220502

Signature is different (almost) every time but as far as I remember no crash felt any different from the two crashes above. For example: bp-093ec6db-d0e2-4f05-8dbd-e03b50220429 bp-47c1b14c-cba2-4007-9f53-089fc0220429 bp-f4ca1090-d760-4209-a47f-8d40e0220429 bp-4a506f38-75ac-4f62-b4bc-324f00220429 bp-d9a19762-4234-450e-82ed-d41940220429 bp-1b0e9da0-29e6-4107-ad7e-ed77f0220429

This bug occurs very randomly, but it seems there have few things in common.

- Occurring on domain level, one domain at once. For example, if Youtube.com stuck, any sub address including each video page is not loaded. Other website and whole browser works fine. - Other program on same PC is not affected, too. - Which page is stop loading is completely random. It might be happen only on a popular, feature-rich site like amazon, google, but not sure. - The timing is also random. Maybe after waking PC up from sleep, but not sure. Frequency of occurrence is once every 1~5 days. - The workaround without restarting browser is 1.)switching to other container tabs(strangely), 2.)opening website on private window. Disabling all the addon manually didn't help.

Since it's randomness, I didn't have any logs about this issue.

I can log into GMail via our SSO just fine, however after a few minutes I see the "error connecting for X-minutes" bar. I try to force refresh the site and every time I get the bellow error. This is also happening when I am using Firefox Troubleshooting mode, to see if maybe it's a plugin/extension causing this issue, but it's not.

When playing music on music.youtube.com, if I navigate away from the tab, by either moving to a different tab or opening a different application the music pauses. This happens consistently with two different Firefox profiles.

I admittedly have a quite a few plugins installed, so I tested this in a private window and this issue does not occur.

I attempted disabling the obvious plugins UBlock, 'I don't care about cookies', and Tampermonkey without any success. I also tried using a different user-agent without any success.

edit: removed erroneous error information

When using built in search (google default) -- browser stops responding. Shows Firefox new tab background when loading the search. Issue resolves on Firefox close and re-open. Paste and go, creating new tabs also fail with same 'new tab background' displayed. Issue is intermittent but appears often, at least 4-5 times a day.

Tested same sample search with google chrome in same time period, no issue.

Issue appeared around the V99 update. Fix would be greatly appreciated - exiting and re-opening browser, dropping all tabs to reload is a serious usability issue.
