Firefox Support Forum

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

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.

Hi Mozilla - I just wanted to report some recent phenomena. In the past couple weeks Firefox, and related Private Browsing browser, seem to have developed consistent hangups in fetching data across a pretty wide range of sites. Both my banking sites will not load after logging in to them, just spins and spins. Also some very general searches will not load any results for minutes at a time, I just give up and kill them. I've uninstalled/cleaned/reinstalled latest version, etc, etc. By comparison, these same data fetches in banking sites, etc, work dandy in Duckduckgo browser, which is also a heavy no-trace browser. This ominous to me as I really like Firefox and do NOT want to have to resort to Edge. Duckduckgo browser is very good but doesn't have nearly the menu or favorites sort of features that Firefox does. Can you investigate? This is typical Win 10 system in Lenovo i7, been working like a champ till just recently, no system changes. Thanks.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

The company I work for is behind a firewall. Our systems running firefox are unable to send crash reports because of the secure nature of the systems. Is there a way I can send the crash report files that I pull from the "Pending" directory and send them to Mozilla manually? FF version snap Mozilla Firefox 103.0.1 Ubuntu 22.04.3

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 keep getting a popup about using an older version and creating a new profile. I already created a new profile a few days ago so I cannot keep creating new profiles every time firefox deploys a new version and would need to open firefox to update the browser version.

Have used Firefox for decades and suddenly it is having problems. If I surf around and have a few tabs open, some of them might crash. Firefox tries to restore them and sometimes it works and sometimes they just crash again immediately. I can go to Amazon and the page won't load completely so I can't do anything. If I try and close Firefox it won't close, it is frozen. And often, pages just load very slowly even though my internet connection is strong. This just started about a month or so ago. I have refreshed Firefox, updated it, and checked the systems on my computer. All my internal diagnostics returned "no issues." So it has to be the program.

When I reboot a Windows 10 computer and click once on the Firefox icon on the Taskbar, (1.) Firefox does not open full screen although when closed it was full screen. (2.) A second Firefox window opens with Yahoo on a Tab and also not full screen. Please fix!

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

When logging in to the online bank at DNB with Bankid, this error appears:

"A communication error has occurred. We are experiencing a communication error between your browser and the user site. The reason may be slow internet or problems with your browser. Try again in a little while. You can also try to delete cookies and browser data in your browser or try a different browser. Error code BID-5000 Reference DXP4VKOE Date 12/06/2024"

No other browsers show this error. I've tried Edge, Chrome, Vivaldi, Brave, CC Cleaner. The error starts after version 125.0.3. Today a new version 127.0 arrived. The same error appears.

I have uninstalled the latest version and reinstalled version 125.0.3. Then no error message appears. I have deleted cookies and browser data, but the error message persists. To your info, I've tried also on other PC's and the same Firefox version, and the same errormessage appear.

I look forward to you having a solution to the problem, otherwise I will have to use browsers that do not show this error. As I prefer Firefox, I don't want to use other browsers. But if the bug can't be identified and fixed in newer versions, I'm not happy with firefox and will use other browsers..

I woke up this morning to my home directory having been remounted as read-only (it has its own dedicated hard drive at /dev/sdd1). I ran e2fsck and things looked good, so I restarted and things were fine again.

However, whenever I open Firefox, it hangs for about 1 full minute before it goes haywire and renders the entire system essentially unusable since being able to access my home directory is vital. The following is visible in dmesg:

All other programs that I use daily do not cause this issue. No clue what to do here. LibreWolf works fine - that's what I'm using now that Firefox breaks everything and basically forces me to restart if I want to use my computer normally.

Hi,

I can't watch live stream on youtube. I see only black screen on loading circkle. Ads working fine but after them i see what i said before. When live is over then i can normally watch it. I can watch twitch normally. There is problem olny on yt. best chris

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

Figma and Google maps are rendering as black screens. I can see control panels, but not content. This has been the case for about a week now. I have tried switching from dark/light modes.

Hello! Since as of last update to 127.0 (64-bit, ARM-version) Firefox looks like the attatched photos. White spaces all over which makes Firefox impossible to use. This only occurs on my Surface pro X though so a problem with the ARM-version?

So far I've tried switching to light theme, a refresh, deleting the entire Mozilla folder in APPDATA and a reinstall (using Revo uninstaller first) of Firefox but it still looks the same...

Is there anything more I can try or is this just my life now?

Regards, // Richard

Hi all,

Currently woking on a Client project and implementing Coveo search engine in Salesforce. However, it looks like Firefox is blocking Coveo and the search is not working at all.

Anyone can help or recommend anything?

Thanks!

Hello!

I get this error often when I try to access various websites. This doesn't happen when I use Opera, so I assume the problem is not with the websites.

My OS: Windows 10. My Firefox version: 127.0 (64-bit).

I have streamed TennisTV in the past no problem but now it stutters and task manager shows CPU 100%. It also shows Firefox running 2 processes which consume CPU and accounts for the 100%. So I closed one of the processes (the one using least memory) and it solved the problem. So how can I stop this second process from starting, it seems to consume CPU without actually doing anything?

When I try to login to my Social Security account after pulling up the Soc Sec site (ssa.gov), I get this message:

"Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

I tried waiting a couple of days and attempting a login again. I also tried turning off my VPN, using a new tab, refreshing the site and restarting my laptop. I do not get this message when I use Safari to login, but I want to use Firefox.

Thanks for your help in fixing this problem.
