I have a frequent problem with dead tabs in FF v121 on Win 10. I tend to have many tabs open (like 15 say) and it sometimes happens that a tab becomes completely unresponsive. It could be a new tab that I open or an existing one that I click on. When this happens I can't do anything. Page reload, clicking on links, entering an address by hand ... nothing happens. The tab is simply dead. The tab is essentially dead. After some time (usually 1-2 minutes) the problem resolves itself. However, it is very annoying as it happens almost every day and sometimes even several times a day. So I am looking for a way to solve, otherwise I will have to move to Brave or some other alternative. Any ideas what could be the problem? I also do not want to restart my browser several times a day as that logs me out of all websites I use including Whatsapp (I delete cookies when closing FF).

I have just reinstalled windows and then Firefox. If I click settings then a menu item it just freezes.

I have uninstalled and reinstalled.

Using Windows 11 Pro 22H2.

Any suggestions?

West Virginia has a website to download old death certificates, but they wont load. There's nothing but a blank page. I'm not positive that it's a Firefox problem, as a friend of mine who uses IE cant load them either, however, she CAN load them on her Tablet. As a historian, I really need to get these records for my research, so I was wondering if someone could go to the site and see of the records appear for them to be downloaded. This is a direct link to one of the records:

link text

While this is the main page were you enter the name you are looking for: link text

If you discover anything, please let me know. Thanks!

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I have been using an old version of Firefox (109.0.1). I am not typically using a newer version because of an essential - to me - add-on which hasn't been updated, and which doesn't work in more recent versions.

On macOS Sierra this old version of Firefox crashes. Troubleshooting mode (I was prompted a number of times) and restarting the browser appears to eventually resolve the crash, but finally there is an issue with the memory and the browser doesn't "work."

The reason for the crash given is " MozCrashReason: Failed to load critical module "resource://gre/modules/WebNavigation.jsm" "

The crash report text is reproduced below: __________________________________________________________________________________________________________________

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

I have tried all fixes suggested by others reporting similar problems with previous versions, but this was noticeable for me yesterday afternoon right after some downtime and the latest version (for me) of Firefox was installed. Every time I try to use a site requiring recaptcha, the wheel spins and I get no choice to log in. I've cleared cookies and my cache, refreshed Firefox, etc. Nothing works.

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.

This has been a problem for a while, currently on Firefox 126.0 and Nvidia 550.78. I can work around the problem by forcing webrender to use software mode.

When using HW accelerated webrender with my Nvidia graphics card everything works fine until the PC wakes from sleep, then graphics are broken and Firefox needs restarting. Most noticeable for me is when looking at Grafana graphs they will look like random lines, and my Frigate NVR snapshots only display some of the time.

Is there anywhere in Firefox that will show a log of any error messages to do with the graphics card? I would like to try and fix the problem rather than disabling HW acceleration, but with no logs to look at that is impossible. No other programs seem to have a problem with resuming from sleep, and no error messages are shown in any of the system logs.

Firefox uses about half a gig on my disk, that's: '~/.mozilla' and '~/.cache/mozilla' can that be reduced? Either some setting that limits disk use or even a manual deletion of ancient stuff?

Version 120 (PC) continuously crashes and asks me to refresh and nothing happens (including after rebooting) so I had no choice to uninstall. I normally trust your updates but I'm really regretting this one. Can you help me not switch over to chrome? Maybe you're already aware of this bug and will have it fixed soon.

I have updated my Firefox on PC to the newest version available (version 120.0.0.8720 as of 24/11/23 00:30 UTC). Unfortunately whenever I try to open it, it loads a blank screen and then crashes, and brings up the crash reporter. This has happened every time I try and open Firefox, even during Troubleshoot mode. I have over 180+ tabs and thousands of bookmarks on my account that I do not want to lose (I have not used Refresh Firefox for this very reason) but if I can't even access them on my computer then what can I do?

Please help me, I want to know how to fix this and keep my tabs and history. I am desperate.

I found a problem with YouTube in firefox, maybe it's related to my computer. When you open and play a video at 60 fps, and at the same time pulling the mouse, the video starts to freeze, it seems like the fps drops. Does anyone know how to solve this problem? Maybe someone has encountered it already?

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

Hello!

I often log in to a service ticketing website to help my customers. Before emailing them I must reference the service ticket number somewhere in the email, but this is very difficult to do in Firefox. If I inspect the element this is what I see:

<em unselectable="on" style="width: 2161px;">Service Ticket #55474079</em>

I understand the unselectable attribute is on but even if I try setting it to off or deleting it all together the problem remains. Moreover, I've tried it in several browsers (Chrome, Edge, DuckDuckGo) and it works fine without any extensions or tricks.

In other words: only Firefox keeps me from selecting this very important piece of info.

Any help would be very much appreciated! I looked up help articles but nothing similar to my case. I did find an extension for the browser but I am afraid to try it due to security reasons.

Thank you!

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.
