Firefox Support Forum

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

Hello, On several occasions over the past couple of months, maybe after a recent update, Firefox will not process any web page. In fact, if I try to go to another tab that I had been using, it will not refresh those web pages. However, in most cases, if I try to open in a new window, it works (though it did not just a minute ago). This is very annoying because if you have a couple of tabs open to certain locations, you have to copy down the pages so you don't have to remember where you were in your work. I would imagine that it would be difficult to duplicate but here's my info below. I will be glad to answer any questions you may have.

Thanks!

we did an update and having issues connecting to our Emr keeps saying not secure website but it is firefox is blocking us can someone call me [removed phone# from support forum] Nathalie

When I click on any link, Firefox opens a new tab but the site will never come up.

I've tried Troubleshoot mode and refreshing Firefox but something in one of the recent updates has caused me to not be able to click on any link and have it open. Troubleshoot mode will solve the problem for a couple of clicks and then the problem returns even while still in troubleshoot mode. Firefox has become unusable at this point but I'd like to go back. Please help.

session is completely gone. I tried to restore it via various help articles and forum posts but without success.

I see a stg-backups-ff-126.0.1 fodler in my download folder which contains information about tabs that I had open. But I don't know how to use firefox to use that file.

I alos tried to the \sessionstore-backups folder with files named like "previous.jsonlz4" but I do not get the menu option for restoring a session.

Hi,

I use ClassicPress (fork of WordPress) and I have a problem when requesting a password reset link for it.

When opening the email received to reset password in the firefox dev edition browser and click the reset link I receive an error stating that the link is invalid.

I discovered by trial and error that copying the same link and pasting it manually in a new tab of the same firefox dev edition browser solves the issue because then the link is recognised as valid.

This happened after the update I received last week.

I am a linux mint user if that helps in tracking down the issue.

If I open a second tab on the screen it says the connection has crashed and keeps doing it if you try again. If you reset it resets Firefox including the other tab.

In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.

Hi I recently upgraded to win 11 and was so happy that god listened to me and you've added PIP to your browser!!!!!! but I have few problems.... most of them I fixed on my own... I have the latest release and I'm using for now the developer edition. I used the regular too but I thought that the developer edition will be more stable. and its not... I needed to buy a new graphics card GTX 4060 OC 8GB just so I can see all the streams smooth without lagging I needed to upgrade to 24GB (I had 12) memory so Firefox will not crash my computer all the time. your memory consumption problem is ridicules!!! :(((( added a screen shot I have i7 4 cores. i ordered Intel XEON X5675 6 cores it should arrive in a few days just so it will be more stable. 1.from time to time it still crashes (submitted my crash report just now) its closing streams and i don't know why. is it Firefox? is it the stream website? is it my computer?? how can i pinpoint the problem?? 2. I'm seeing multiple live streams usually 6 or more with PIP , I'm organizing the layouts so that I can see them all together. I've sent you a screen shot. for some reason the streams windows keeps centering themself to the borders of the actual screen its driving me nuts. like it has a mind of its own. I keep moving it beyond the border so i can see al the streams but after a minute or two it keeps moving back to the actual screen border. sometimes it doesn't move. its like AI is controlling when it moves and when it stays. is there a way that a computer program!! will listen to my command instead of having a mind of its own and moving my stuff to where he wants too?? is there a fix to it???

Whenever I try to watch a video on YouTube, Firefox would automatically set the playback speed to max, mute the audio, and the video would just end (as if someone moved the seek pointer to the end). Since my YouTube is set to automatically play the next video, I would be presented with a screen showing me what the next video would be playing. At this point, I need to do the following:

1. quickly click cancel
2. hit the replay button
3. set the playback speed to anything but normal
4. set playback speed to normal
5. unmute audio
6. move seek pointer back to beginning

From this point on, videos would play normally and I can jump around and watch different videos. But once I close Firefox and restart it, it would reset to the above issues (max playback speed, mute audio, skip first video).

Anyone else having the same problem? Anyone know what's going on?

On a tangent, on my Windows machine, every now and then, Firefox would flash a white blank screen. I would be surfing and reading stuff and all of a sudden, the screen would just go blank. After a few seconds, it would come back. This only happens on my Windows machine and not my Mac.

Hey,

I constantly have unreadable fonts in Firefox for Mac. This only happens since I started using a new Mac (M2 Chip).

I know there are some "solutions" flagged but I cannot get it to work. My main issue is, the inspector it self has completely garbled fonts. So does the elements of the browser itself, for instance my favorites bar.

I know I am supposed to check my fonts, but I don't know how? I used the fonts application on my mac and let it validate the fonts. No issue there.

Only thing to resolve this issue is to reboot. And this is extremely frustrating since it means out of the blue my Firefox won't show fonts and I have to save all my work and reboot to be able to use it again.

I would highly appreciate a step by step solution on how to fix this. It seems to be a common problem so maybe there is a solutions that describes it better than the text I found here to inspect elements and check fonts.

Thanks in advance.

Hey everyone,

When I opened firefox this morning, I was notified of the update 127.0 update. I have auto-update enabled. Since the update, my browser experience has reverted back to 1999, where opening a tab is slow to a crawl, scrolling on (for example) facebook is delayed, and youtube videos keep buffering.

Note: I have a beast PC with 36GB RAM, and a 1000W PSU, yet in my task manager it stays as using almost 4GB of RAM and "Very high" power usage.

I've updated drivers, tried the "firefox safe mode" which had the same issues, and confirmed that this doesn't impact any other of my internet-based activities (like gaming and discord).

I've also run a malware check (deep scan) and found nada.

Lastly, I've tried ye-olde 'turn it off and on again'.

Nothing has helped. Any suggestions? I'd love it firefox had a revert update feature but it does not, which is a huge bummer. Please gimme a hand, 'cause I hate Chrome, which is working just fine.

Sometimes, when I try loading a webpage that uses WebGL, the WebGL elements won't display and it'll show a black area where the elements would be, and the only way to fix it is to restart Firefox. This doesn't happen all the time, but it happens enough to be super annoying.

FF just did an update and now I can barely use the browser. Its slow and then spins and crashes... it took me 6 minutes to just get this open and type this. All my links and sign ins are on it... ugh... How do I reverse the update? thanks

Hi All,

This salesforce site is working in safari, chrome and edge but it is not working in the latest Firefox browser. It crashes after getting stuck for minutes. Is this technology not supported by Firefox?

The lag is very problematic to me, because I do most of my work using the browser. When the keyboard starts lagging I can only enter text using copy/paste with mouse (which works fine). The only way to solve it is to restart Firefox (which can result in lost work).

The lag, when it starts, is 10 seconds or more for each keystroke. It occurs about once every few days.

Ubuntu 22.04.4 LTS

126.0.1 (64-bit) Mozilla Firefox Snap For Ubuntu Canonical-002 - 1.0

I don't use Wayland.

Setting accessibility.force_disabled to 1 did NOT help.
