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.

Racenet is a formguide put out by News Corp and subsribed to by mug punters like me but i am unable to download it with the message 403 ERROR the request could not be satisfiedbold text

After the last update, Firefox won't open. Instead, I get this message:

"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window."

I have closed it within the error message but the error message comes back each time I try to open Firefox.

Please help, Deb

Hello,

I'm troubleshooting a Firefox Desktop issue that I haven't been able to reproduce consistently in other browsers.

I use a browser-based precious metal calculator that performs calculations instantly using JavaScript. The page loads correctly, but after changing several input values and navigating between tabs, Firefox occasionally continues displaying an older calculated result until I perform a hard refresh (Ctrl + F5).

I've been able to reproduce the issue consistently using this scrap calculator scrap calculator. The page loads normally, but Firefox sometimes continues displaying an older calculated value until a hard refresh is performed.

The page itself loads normally, and there are no visible JavaScript errors in the Browser Console. However, the displayed value sometimes does not update immediately after changing the weight or purity inputs.

So far I have tested:

• Firefox Troubleshoot Mode
• Disabled all extensions
• Cleared cache and cookies
• Tested a new Firefox profile
• Disabled Enhanced Tracking Protection for the site

The issue appears only in Firefox Desktop. Chrome and Edge update the calculation instantly under the same conditions.

Has anyone encountered similar behavior involving JavaScript-driven calculations, form inputs, or page caching in Firefox?

Are there specific Firefox settings or diagnostic tools I should check to determine whether this is related to caching, page state restoration, or another browser feature?

Thank you for any guidance.

Has anyone reported this before? I am working as a contractor for a BigTech company. I am using an online platform/tool of theirs for several years now but after a recent update the work area doesn't show scroll bars anymore. That means I cannot scroll the editor window and can't go beyond the first page. This makes working (and earning money) almost impossible. As even for the tiniest edit I have to download huge tasks which is extremely time-consuming. An inquiry with my manager there indicated that other contractors on firefox experience the same issue. so they consider it a firefox compatibility issue of some kind. They gave me the advice to use Chrome, Edge or Safri instead. Well, I use firefox because I do not want to use Chrome/Edge... Don't know about Safari but my PC is on Windows... Any idea what can cause it and how to resolve the issue?

Hello! I'm working on migrating a very old version of Firefox to a newer version, and the number one thing I want to make sure stays is the logins file(s). I went to export the CSV, and the `about:logins` page is blank! Despite this, both the key and logins files are populated, and the browser still autofills in each login as if it wasn't there. To mitigate this, I tried to export the .csv of all my logins, but it doesn't actually export. I'm not sure how to check action logs with Firefox, and I would like to grab the passwords, so I can migrate properly. Any advice would be appreciated. Thank you!

PLEASE HELP! One day last week, Firefox for my PC disappeared and it seems that Duckduckgo has taken over. I have used Firefox on my PC for a few years and occasionally use duckduckgo as my browser. Now I cannot find Firefox. It is up-to-date, as of last week.

Please Help RhonCa

And problem contines after several patches. The firefox version that I use is "153.0.3(64-bit)" please help!

DRM nags are back ! I am very suspicious of this ! Stopping FF DRM nags yields NO search results -- but used to. Zero searchable information in the Mozilla databases. What a search for DRM nags does yield is LOADS of outrage (see attached) against FF. I am getting a VERY, VERY suspicious. Before FF tries to monetize more functions -- FIX THE LEGACY ISSUES !!! One thing after another, all week, month and year. 'Upgrades' of the browser induce panic and fear these days. "What will break next ?". You people need to look at shrinking market share and growing outrage and have a Come-to-Jesus moment ! Pawning off 'support' on volunteers is about as cynical as I have ever seen. No useful answers for weeks to many things I have posted since migrating machines to Win 10/FF 15x.

Glad I did that search ! "Back in February, Mozilla changed Firefox's Terms of Use and Privacy Notice for the worse. Mozilla removed a longstanding FAQ promise – Nope. Never have, never will" – regarding the sale of your personal data to replace it with a less definitive pledge" to "protect your personal information." Would it surprise you to know that a few weeks later, Mozilla announced that AI would be its top priority in 2025? I note that this was listed above privacy." Where the Hell is the AI Plague going to get a broken browser ? Look at those damn search results ! Gazillions of posts by fed-up users and vastly shrinking market share.

Looking for an exit now...

Added by FF - poor move on FF part. Unlike others, can't be removed any of the "traditiona" about: methods.

Need to have it go - we DO NOT want this used here.

So I know these websites are kind of crap anyway, but I have issues with scrolling bsky.social (and other clients for it like witchsky) and twitter. The further into the timeline I get, the more frequently these webpages lag.

They begin freezing every few seconds for a few seconds, during which they queue left or right clicks, page up/page down, and various other commands, only processing them once it unfreezes. Firefox itself still works during this freeze, e.g. opening the main menu. Also, I can still scroll up or down to a limited degree, though this just exposes empty, unrendered webpage until it unfreezes.

bsky.social has had this problem for a long time, but twitter only recently developed this issue after I had to do a cache clear, cookie clear, etc. trying to log in a few weeks ago. Prior to that it didn't have this issue.

Task manager hasn't really helped elucidate what's wrong, so it might be an about:config that I set or even an unruly extension, but I really don't know what to try.

Every time I open Firefox I get a message saying "Getting close to your VPN Limit. You have _ GB left. Your data will reset at the start of next month" and I want to stop seeing it
