Firefox Support Forum

Firefox has crashed repeatedly when I've switched tabs to my gmail in the past ~15 minutes. It happens in "troubleshooting mode" as well. I'm running firefox on a linux computer, and my ubuntu installation and firefox are both up to date.

Here's my crash id: bp-b079d597-fb83-4a69-ab65-896370231129

The latest updates sucks. Trouble with log -in pages, even Mozilla's own page doesn't seem to like the new cookie settings... Had to get onto tis forum through chrome of all things...

Anyone aware of fixes or some way to revert to an older release?

Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

The "Layout.css.page-size.enabled" configuration parameter = False ,worked effectively in previous versions, but after updating to Firefox 119.0, it no longer works whether I set it to True or False.

Orientation option is missing when I try to print documents from a website. The Firefox Print Preview window, which usually allows orientation choices for printing, is now not available.

Please advise. Thanks!

I noticed today that a video hosted on the website Reddit has subtitles on it. When I view the video in other browsers it does not have subtitles. Why are subtitles being generated in Firefox for this video? Is there a way I can disable these subtitles? While often useful, the subtitles in this case just get in the way.

If URLs are allowed one example is here: https://v.redd.it/z7tekckuy9hb1

Thanks.

Our IT specialist at UW-Madison is stumped and suggested I reach out to Firefox. He was helping me troubleshoot why Firefox keeps saying it's sending a code to verify my account, but I never receive the code. He has added the "accounts" email to my contacts and I don't know what else to do or try. Any ideas from the community? I need my bookmarks after upgrading to Windows 11 and can't imagine trying to recreate them all.

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?

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

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

Firefox with only this tab I am submitting this to, NO extensions as it is a brand new OS/machine, memory over half gig, in firefox task manager, GPU is over 300mb. This makes the browser literally unusable, tried resetting, renaming the profile file, logged in with my account, turned off hardware acceleration, rebooted the machine, nothing works...

I get this error when trying to access my email using FireFox. Lately this (or a similar) error happens weekly if not every couple of days. Always first thing in the morning, too.

my email works just fine using Safari so I am at a loss.

I have tried running FF (Firefox) in safe mode, ensuring outlook.live.com is an exception to the pop up window blocker, changed default protections on outlook dot com to none from standard.... Turned off ABP, clearing cache and cookies from within FF.

it may be worth mentioning that I can still browse/access other websites while outlook produces this error, and my network settings within FF are set to use default system settings (no proxy).

Since the Firefox update released 2 days ago (version 115.0.1) I'm constantly having an issue which causes the video to stop playing after the adverts. I eventually get a video unavailable message. I've cleared my cache but it's made no difference. I'm hoping that this is a known issue & that someone is investigating ?

Is there a memory issue with Firefox in regards to how PDF files are shown?

This happens every so often.

When I open a PDF the font is distorted and it seems to be encrypted. I have to close Firefox and reopen and then the PDF file is displayed correctly without any issue.

Thanks.

Hello! So the problem I'm having is every so often after ten minutes of Firefox working perfectly it will stop working. For example, it won't load any new pages it'll just be stuck pinging back and forth. The website will stop loading YouTube and Twitch will show network errors etc. And it's NOT MY NETWORK or router.

I'm hooked up threw an ethernet cable but my CPU and ethernet ( I just got a new ethernet cable CAT 8 because I thought it was my cable but it still doesn't work) only spikes when using Firefox it's like Firefox stops sending and receiving. Yet other browsers like Chrome work PERFECTLY. But I would prefer using Firefox since all my bookmarks and things are saved here.

I've tried clearing my cookies etc. I'm going to try redownloading Firefox but if there is anything else I could do please let me know. I have some images attached one of the balls just loading and I'll be waiting forever until I restart Firefox. The other is of a media player that says I have a network error but I only get this error on Firefox.

Thank You

Hey all,

I have a few customers that use Firefox and the last month everyone has experienced an issue with tabs constantly crashing. Everyone is on the latest version and there really doesn't seem to be much rhyme or reason.

I've tried: -Doing a clean install -FireFox refresh -Disabling Extensions (we only use uBlock Origin) -New Profiles

Not sure if this is normal but there's nothing in 'about:crashes' after it happens (i assumed because it's just tabs and not the browser itself).

These are all Windows 10 machines.

Any help would be greatly appreciated!

Hi there, Last night I installed some new hardware into my PC, new motherboard and CPU for example. After that, I booted up the PC, everything worked completely fine and I was able to listen to Youtube / Twitch / Spotify etc. through Firefox.

This morning I boot up the PC, everything still works perfectly and I have audio coming from all other sources EXCEPT for Firefox. I have browsed every forum already but can not find anything that relates to me. I can't set my output device, since Firefox doesn't show up in the volume mixer. The tabs aren't muted. I have restarted Audiosrv and Windows Explorer several times. I have re-installed Firefox twice. I have tried booting it in safemode. All of the above hasn't resulted in a single second of audio. I am at a loss.

Kind regards, Siem Hoefnagels

I now have 115.0.3 and this problem still exists. It was reported right after 115.0.1 was released. When watching FreeVee on a Windows 10 desktop it stops a short while after an ad plays. It looks like it loses the ability to stream the main movie while streaming the ad. After the ad it plays about 20 seconds of the movie, probably what was in the buffer before the ad started, and then it freezes. I get the circle wait icon, like what typically happens when the Wifi goes down. After a while a message appears saying the Internet is not working. See attached image. Then I get the message (see other attached file) saying Video Unavailable. We're experiencing a problem playing this video. For assistance, please go to www.amazon.com/videohelp. Close Player.
