Форум поддержки Firefox

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

If I go to Safelite and start scheduling an appointment, navigating through that set of webpages will cause my computer to green screen/crash. The landing page at https://safelite.com asks for a zip code, and submitting that form puts you into the scheduling flow; after entering some details about a vehicle, I can click back and continue a few times (less than ten) to make my computer crash. I was able to reproduce the issue in troubleshooting mode. I also tried the same steps in Chrome, but it did not produce a crash.

This computer has had an issue with crashing in this manner for a while now, but this is the first thing I've noticed consistently causes a crash. I'm not expecting a solution, but I am hoping to close in on the issue; whether or not Firefox is the source here is questionable, but it does seem highly entangled.

No matter what I do FF always opens to the "Success!" screen and wants me to choose what tabs to restore. I have done troubleshooting mode, clean mode, refresh and complete uninstall and reinstall. Nothing works.

Hello,

I am using the Flatpak Version of Firefox on Manjaro Linux. I have hardware accelerated video playback on Youtube for VP9 but not for H.264 on YouTube and Twitch. I can verify that with intel_gpu_top. My hardware should be capable to do hardware decode. You can see in the provided screenshots, that it should work from the configuration standpoint. Do I missing something here or is this maybe a bug? I can provide any further information if needed.

Firefox use 100% of my cpu and drops frames when playing 8k video (gpu acceleration setting is turned on). Chrome instead have no frame drops and does not use 100% of the cpu.

I tried to google it and use some solution, but no effect in my case.

hardware: cpu: ryzen 5600x gpu: rtx 4070 ram: 32 gb monitor: LC27 JG50QQIXCI (qhd 16:9 144hz)

PS: 1st picture firefox, 2nd chrome.

Any method I open a new tab, it always takes up to 7s to load, while completely suspending my browser. This also happens in troubleshoot mode but not in incognito. Directly opening websites in a new tab doesn't trigger that bug. I don't recall when this started to happen, it might be after some new Windows update.

I have included screenshots from Firefox Profiler, both from regular window and incognito one.

my firefox youtube is broken, every time i close firefox, and open youtube, the comments and the sidabar wont load, until i clear my cookies and login. so that fixes it, but its not permanent. if i close or restart firefox, id have to repeat this process again. and yes, ive disabled all my extentions and cleared cache. and updated firefox.

Firefox has recently (within about a week or so) begun to crash randomly for me when switching between open tabs. The problem can be reliably replicated with ~6 tabs open, while quickly cycling between them. Firefox has been updated, and the crash still occurs even in troubleshooting mode. The most recent reported crash is Crash ID: 54793083-0841-470c-ae8a-687030240105. The flagged 'Crash Reason' is EXCEPTION_ACCESS_VIOLATION_WRITE

Online forms don't appear in Firefox (Windows 10 PC), but do appear correctly using Edge or Chrome. This has been happening for quite some time. I have o switch to Edge or Chrome to see the fields to fill in on online forms.

Hi everyone,

so I just started firefox on windows 10 and updated it to version 121 and after that all my saved passwords are gone. Completly. Tried to restore them over my ios firefox but because of the sync feature it had already replaced the saved passwords there too. What is odd, that I am still logged in on couple of websits but the login data for them is nowhere to be found... Ofc I don't have any backup so I am probaly screwed here. I don't understand how that could happen in the first place... Has someone else experienced this or mabye has any advice how to resolve this? Any help would be appreciated.

Kind regards Fabian

Long-time problem: Running Firefox 115.6.0esr (64-bit) on Windows 7 Home Premium SP1 (64-bit). Viewing "CNN live" in one tab. Mutes if I open any another app/window [Login to website #1 [CNN live] and view/listen...Open anything else; CNN mutes] (Note- This happens in both Firefox and Chrome) Any ideas/suggestions for how to avoid this behavior? Thank you, Ron

Chrome is fine.

Apps Firefox and Thunderbird are having problems opening links to webpages. In particular, Cloudflare cannot verify (it just cycles between a checkbox "Are you human?" and a browser check) when I use FF.

I use Win11 with NordVPN, but this wasn't a problem before the latest Win11 update. (It also seems to have affected TB reconnecting to Ymail.) I'm now using Chromium to read my Ymail avoid Cloudflare verification, but I'd rather keep using FF and TB apps.

I've been going though Cloudflare, NordVPN and Mozilla online help for a few days now, and I think I've tried everything there.

Thoughts?

When I start typing my cursor disappears. It does not reappear until I've clicked a few times or wiggled my mouse a lot. This is quite an inconvenience, and I've tried to find a solution for far too long now. This also does not seem to affect any other application other than Firefox.

I have set both widget.windows.hide_cursor_when_typing=false and hideCursorWhileTyping=false I have also verified that there are no OS-level options set for this behavior, although I feel the above settings should override OS settings.

System details: Firefox 121.0 64-bit Mozilla Firefox for Ubuntu (non-snap) Ubuntu 22.04.3 LTS Gnome 42.9 Experienced on both X11 & Wayland

Please let me know if any additional information is needed

It worked nicely for many years, until today. I installed Supraland from Steam, played for a couple of hours, and suddenly my Youtube page went glitchy - not the layout but minor elements were getting scrambled, especially text. I'll attach a couple of pictures to show it. In fact, all pages glitch if their content changes even a little. As of typing now, I see the glitches, with a word or another getting butchered. Gifs and videos are full of that.

Windows 10, the current update, Radeon RX 580, the recommended AMD drivers installed (and reinstalled again and again, 23.11.1)

I think I did pretty much everything with Firefox. Disabling hardware acceleration fixes it (but then of course the browser goes slow). Games work fine, including Talos Principle 2 which is intense enough. The clean install, reinstall and all that. I'm writing from the beta stable build now. I've tried to regress to the previous versions too.

It strictly coincides with the game installation but I have no close backups - who knew that some game might just do that. Then, of course, I tried to uninstall it too.

Thoughts?

It turns out the copied logins-backupjson file i had pasted on my desktop screen was already overwritten by an added or removed login, thus writing over when it did have the saved login removed that i was trying to recover

is there any other way to recover the removed login?

i saw this response by Cor-el for another user with a similar situation

If you still have the signons.sqlite that was used in a previous Firefox version then you can try to restore passwords saved in that file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed). If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions). You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:

   reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
   delete the logins.json file in the Firefox profile folder with Firefox closed 

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.

Hello, I am running Ubuntu 22.04 (Firefox v 121.0) on a custom PC. Ryzen 5700G, 32GB Ram, 2TB Storage, and a Radeon RX 580 (just to give some insight into the system in case it is useful). I use multiple mozilla services and haven't had many issues up until now. Everytime I open Firefox it immediately it fires right up, the moment I try to open a tab, search, etc.. it begins to lag. It will then freeze the browser and my entire PC soon follows suit. I have had to hard reset the PC about 3 times now. I originally had the snap version installed and thought that installing the deb package would fix the issue. I completely uninstalled the snap version and turned off unattended installations in case the system tried to reinstall the snap. I then installed the deb package and fired it up again, only to have the same issue. I have ruled out a couple of things on my end. I entered Firefox Safe Mode and unchecked all of my extensions (the only ones I run are Ublock, Bitwarden, and Relay). I ran a mem test and have been monitoring Psensor to ensure the CPU wasn't overheating (both of these tests were fine). I also scanned my entire PC to ensure I did not have any viruses (clamscan reported no viruses). I have been running my PC for about an hour now without starting Firefox and using Chrome, and I have had no issues with freezing or anything similar to what happened with Firefox. Not sure where to go from here. I love using Firefox and would love to get back to surfing as soon as possible! Any tips/help would be greatly appreciated! PS I could not find any logs about the session. I looked in ~/.mozilla/firefox/Crash Reports/events and couldn't find anything. If there is another place they are stored let me know and I would be happy to send them. I just don't want to open Firefox until I feel it is safe for my PC.

I forgot to add: I disabled hardware acceleration as well, did not fix the issue.

I attached a screenshot of what appears whenever I click anywhere around any text. It acts like it's a place that I could type. Obviously not something that breaks the app, but incredibly annoying. Also only happens on Firefox.

What would I have to do to get this to stop? It surely can't be an intended interaction.

Firefox displays text on the .xml page as html code instead of rendering is as normal text. The layout and images on the page look as they should.

There is nothing wrong with the page, as it is rendered perfectly in Chrome.

In addition, this page doesn't display at all on the phone. When I click on the link it asks me to download it and then asks me which app I want to open it with - instead of simply rendering the page.

I have seen some old threads on this topic, it looks like this issue haven't been resolved for few years.

My question is not just about fixing it in my browser but at the root cause. This page is the RSS feed of my podcast which many people want to access and many use Firefox as their browser. Unless I tell everyone to use Chrome instead.

Can someone help? thanks.

Hello !

I am trying out a Linux (Fedora 39) with enhanced privacy (hardened firefox with the user.js from Arkenfox). My problem is the following : When I quit a video that was in full screen with Esc. the inner window dedicated to the webpage resizes to a smaller one such as the one seen in the screenshot.

I fixed that by going into troubleshoot mode and the window went back to its original size and then reactivated my extensions but the same problem appeared when following the process aforementioned.

Any idea what could be causing this ?

Best regards,
