Firefox Support Forum

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.

I've been dealing with this issue for a long time now, without finding any solution

On macOS, whenever I am using Bluetooth headphones (Sony XM4, Airpods Pro), videos will hang for a few seconds just as the video is starting. This happens again if I pause/unpause or if I seek forward/backward on a video. The video "spinning animation" will appear and it will take 2-3 seconds for the video to start. This happens immediately, even if I click pause/start fast (ie: this is not after some delay necessarily). Also, if I mute audio on the video, the issue does not manifest itself.

During the waiting, Firefox itself seem to be hanging: for instance if I click on an extension icon in the toolbar, nothing will happen until the video finally start playing and then the extension menu will open up

When using Google Meet or Zoom for instance, I sometimes have to wait up to 10 seconds or so before Bluetooth Audio/Microphone starts after I've joined a meeting.

The issue is not specific to these platforms: I experience the same issue on other platforms such as Facebook, dailymotion, vimeo, zoom. On Facebook, since videos start muted, I can see the videos start playing right away, and then if I unmute sound the video stops, and start again with sound after 3 seconds or so

The issue does NOT manifest itself when playing an audio-only stream: ex Soundcloud or local radio stations audio stream

Things I've tried and didn't help - Troubleshoot mode - Different Firefox profile - Different Firefox install - Restarting my system

This feels like Firefox/macOS is waiting for Bluetooth to activate, or something like that. I have a feeling this only happens for certain types of video/audio codecs but I am not sure how to validate that (ex: no issues on soundcloud, petron audio-only posts).

The problem is entirely non-existent when I'm using sound output that is not Bluetooth.

This does not happen with other browsers otherwise I wouldn't be posting here :)

I receive e-mail from websites where I subscribe. Many times, the message from the sites (kelbyone.com, to name one) contain a graphic (jpg) that does not display in Outlook.com. Microsoft Tech Support is unresponsive. The sending websites refuse to help.

It seems to me that FF chokes on the length of the hyperlink. Here is a sample: https://kelbyone.acemlnb.com/lt.php?x=3DZy~GE2JaTN5XV.-wy5heOd~nAnuwAjluw2Z5PEIaOb5p8qy0y.0uJz2nRzit~yjvYwXncWJXCf657

If I paste the hyperlink into the search window, the page will load. When I forward the e-mail from Outlook to yahoo mail, the image displays.

I am running extensions Adblocker Ultimate and DuckDuckGo Privacy Essentials.

I would like help with this, at least, to identify where the problem is.

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.

Hello,

Relevant system referenced below:

MacBook Pro 2021 Mac OS 14.5 Firefox 126.0.1 (64-bit) Carbon Copy Cloner 6.1.11 (7673)

I have a case of vanishing bookmarks. I quit Firefox last evening with command-Q as I’ve done a thousand times before. When I launched it this morning I was greeted with Firefox with an empty Bookmarks Toolbar and “Getting started” message. I opened a Manage Bookmarks window and everything there was empty too. I found, as well, that all of my saved UIDs and passwords were gone except for three, two of which I haven’t used in months. Weird.

Next I opened Firefox Help and found information about Troubleshooting Mode; I restarted in troubleshooting mode but nothing had changed. After restarting in normal mode, I tried Restoring Bookmarks; I chose Manage Bookmarks from the dropdown and then clicked the button in the Library window. Restore showed only one file and it was created today with only 14 items. Selecting Choose File… showed Desktop with Old Firefox Data highlighted. In that folder was only w34y3u9y…628 folder. From there I selected bookmarkbackups and the only file there was bookmarks-2024-06-06_11…lz4, a file created at 3:33 today. I found the key4.db file and it was created at 3:33 today.

I have Carbon Copy Cloner and use it for a weekly backup to a remote SSD drive. There are a year's-worth or so of weekly backups on that device. I tried trashing Firefox and reinstalling it from last week’s backup. While this worked, it didn’t solve the issue; it was still like a fresh copy of Firefox with no bookmarks.

I’m hopeful that I can restore the bulk of the lost bookmarks from CCC but I have no clue as to which files/folders to restore and I don’t want to guess. If you think this is possible, please tell me which files or folders to replace. Should I delete the files to be replaced from the current system and if so where are they located? I’m comfortable using Terminal for basic purposes but need explicit directions for entering commands and navigating to locations or files.

Thanks for your time,

David

When downloading a file in Facebook Messenger, Firefox changes file extension to .pdf. My case was .docx file but looking for help found people have problem with other formats, even non document saving as .pdf.

Not asking for help, just reporting problem

I was able to use it normally before, but when I downloaded a file, the browser froze, so I used Task Manager to terminate Firefox and reopened it, and then I encountered this situation.

When I open the "Downloads" in Firefox, the browser hangs and prompts unresponsive. I have tried the troubleshooting mode, but it did not work, the problem still exists. I also tried to "Refresh Firefox", but this did not solve the problem either. I also tried to delete places.sqlite, but it was also ineffective. Then I created a new user profile, but the same situation occurred. I also tried to uninstall Firefox, delete AppData/Local/Mozilla and AppData/Roaming/Mozilla, and then reinstall it, but it also couldn't solve this problem. I've had this problem on both 126 and 125.

Dear Support Team,

After updating to last Mozilla Firefox version (126.0.1) all my ngx-datatable tables are overlapping all rows over the first one even if the entire height of the table is correct calculated.

This is a blocking point. I need assistance urgently.
