Firefox Community Forum

Hi, I'm having this problem on 2 PCs and I'm not sure what in the world is going on. It's not only this browser but I'm trying to get Firefox sorted.

When on sites like Walmart or Costco I'll be scrolling down, click on something, hit 'back'...and then it won't return me to where I left off.

I'm really at wits end. I don't know if I have viruses on both causing aberrant behavior.

If the internet were in it's infancy last century, this would be understandable...or again maybe I have two compromised machines. I'm on the Malwarebytes forum doing all kinds of things to no avail. Defender and Malwarebytes don't find anything.

Thanks if anyone can provide some help. I'm starting to consider a dastardly ipad at this point...

Title says it all, "auto resize pictures using CTRL - + does not work". Generally speaking, the size of pictures simply WILL NOT reduce in size to view its entirety. Even when the scroll-bars are used the picture is still to wide. I have searched and asked for any setting in about_config, NOTHING! I truly expected something. The ONLY STUPID WAY to view said oversize picture is Download it then view. Isn't that a HACKERS DREAM??? YES I HAVE tried looking in SETTINGS and searched for months, found nothing that actually works. So now I have to use that 4-LETTER word... HELP!

I can't download some pdfs, notably my bank statements. I CAN download some pdfs. Eg, I can download my car manual (although it's a process of downloading it to my Google Drive). However, trying to download my bank statements, Firefox gives me no options at all, and, indeed, I get an error message. Yet I CAN download my bank statements using Google Chrome! I've carefully checked all my Firefox settings, but nothing seems to address this problem. I've spoken to my bank, and they don't know why I can't download them either. When I try to download the statements, I get a screen saying it can't give me a 'Preview' (see attached screenshot), but there's a 'Download button. When I click that I get a white screen with the 'error' message:

"No API key found in request. request_id: d52e0732a3d10a75b1ec58534845c15c"

(2nd attached screenshot.)

I have asked about this before on this forum, but to no avail.

title sums it up mostly. I've entered troubleshooting mode; no discernible difference. When I switch profiles the issue is resolved even with the same YouTube account. Tried clearing the cache, nothing. Most recent version of Firefox, windows 11.

Last month I installed Firefox on my brand new Windows 11 PC. The PC is set up using UK English as the default language and all the applications, including Norton extensions in Firefox v 153.0.3 (64bit), install in English.

The one exception is the Norton AntiTrack extension downloaded and installed from MS Store. It installs in English on MS Edge, but on the same day installed from MS Store on Firefox in French.

I have uninstalled AntiTrack and Firefox from my PC and then reinstalled them after rebooting, but it still insists on reinstalling in French. I can find no way to change the language setting in AntiTrack.

Does anybody have any suggestions to solving this problem.

NB AntiTrack also installs in English on our Android tablet and phones.

Please help, it looks like my passwords are not synced anymore on any Mozilla I use. I sue a Mozilla portable at home and a classic desktop on my office. The synchronyzation works for bookmarks, browse history and download history but not a single password is imported on my sessions ! My files are present : see screenshot01 so my passwords are here. Login.json contains data. So what's the problem. The debug mode said that : see screenshot 02 Thanks for the help

TL;DR: I am dumb, but not an idiosyncratic web browser user, and it was too easy for me to accidentally permanently delete all of my browser data. Deleted profiles should be moved into system trash when deleted, not rm'd entirely.

I have never used "profiles" and somehow, after updating firefox, seemed to have created one. I have no interest in using the feature, and therefore went to delete the new profile and disable the feature. Somehow, I instead deleted the profile I had implicitly been using all along. I clicked too hastily through the warning about deleting files, because it simply did not occur to me that deleting something related to this net-new feature should clear all of my *old* data. My goal was to restore the experience I've had in firefox for years (without profiles), but because I failed to adapt to the new feature, I lost everything instead.

I apologize for maybe shouting into the void about this, but I am posting on the off chance that this will reach someone who's involved in the implementation of these features and can save some other dumb person like me from making the same dumb mistake. It's quite painful to suddenly lose years of accumulated bookmarks, extensions, history, etc. The easiest and least intrusive solution would be to always move profiles into system trash when they are deleted, and never permanently delete them.

After the most recent Firefox update all my bookmarks were scrambled. For example, when I open one marked Bank of America, I get Go Daddy. How do I restore my bookmarks to what they were before the update?

I use a paid for subscription to Gemini AI. It often creates "visuals" for me apparently using JSON code. These do not show up at all. Moreover, the buttoms and other UI controls do not display well in Firefox. Is there a way to fix this?

Background: On August 6th morning EST after the August 5 2026 update, attempting to use firefox lead to the window with the "end process" button so I had to close the browser multiple times and then the next time I opened firefox, the bookmarks and history were wiped. I was able to restore using a backup saved on the computer and continue as normal (aside from losing some Cookie Clicker progress, reinstalling Tampermonkey userscripts, and redoing browser extension settings) but now there's an issue with trying to backup firefox data.

Issue: Trying to back up my firefox data leads to a "There was a problem backing up. Try again in a few minutes."

When going to about:config and typing browser.backup.backup-debug-info, I get {"lastBackupAttempt":1786243812,"errorCode":9,"lastRunStep":13}

When looking at Broswer Console, there is an entry saying BackupService: Could not create C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini: NotAllowedError: Could not write to `C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini': failed to open file for writing (NS_ERROR_FILE_ACCESS_DENIED) BackupService.sys.mjs:4116:23 but I don't know how to address that.

High contrast setting only support 2 colors(unvisited links and visited links) as a consequence it does not support radio buttons(switches that move to left and right to turn on features). the buttons are invisible and waste hours of the users time.

I have three email groups on Comcast.net. To view the members of these groups when using Foxfire, I have to put them into the addressee box. However, if I use MS Edge, I have no trouble viewing them by opening the group using the usual prompt. This has been going on for a long time. I am running Windows 11, but don't know the version of Firefox, just that it has been updated several times since the problem began.

I couldn't see password management page. To be specific, I click the "password" option in the top right corner lists. Normally it will show all the website that firefox saved, but now I couldn't see anything except frame. I will upload the interfance that I see. this problem happend since an update. And problem contines after several patches. The firefox version that I use is "153.0.3(64-bit)" please help!

It seems to be related to video playback but not sure. It was happening while a video was playing full screen, and also after stopping playing/hiding a non-full-screen video.

To catch the issue had to screen record at 240fps. I used Nvidia Overlay to record the issue, but was happening before the overlay was even enabled.

Disabled all addons, made no difference. HW acceleration on or off, still happened.

I tried turning on logs, and this always seemed to show up with the flash: ``` 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 ```

Hello, i recently upgraded from a 4k monitor to a dual 4k ultrawide monitor, and have been having visual issues specifically on firefox and no other applications. when firefox is out of focus and i have a different window selected, the text in the firefox window becomes blurry

Hi. Every time I go into youtube, the sound cuts out after about an hour. I then have to go to settings, volume mixer and Mozilla Firefox and click on the X to get the sound back. Youtube has assured me this is not their problem, but a Mozilla one. I've been with Firefox for many many years and have never had this problem. Could you please advise me as to what to do about this ? Thank you.

I want to make the switch from Chrome to FF (to continue using UBO), and a problem I keep running into is media not displaying in Twitter(X)'s DMs while using Private Browsing mode. It only comes up as a gray block that says "Failed to Load" with "Retry" under it, but it never loads. It also asks that I re-enter my DM password every time the page reloads.

Everything works fine in a regular browser tab, the issues only occur in Private Browsing.

I have tried disabling UBO, disabling Enhanced Tracking Protection, and clicking the little shield icon in the URL and turning that off, too. Looking this up really didn't give me any results that actually helped, either.

Help would be much appreciated! This really is the last big hang-up I have to not switch.
