Firefox Community Forum

I want to upload the current version of Firefox. However, the system Administrator (who is me) will mnot allow me to do so. How do I change settings to allow for the upload.

Firefox lived on my computer for three days. On May 30th I installed the latest version of Firefox Developer Edition. Today when I launched my browser I saw a page notifying me that my version of Firefox is the latest [152.0b6 (64-bit)]. All installed extensions disappeared, the connected profile was deleted, the .mozilla/firefox directory contained only the newly created profile... No history, no bookmarks... No crash reports...

What happened? Now I'm afraid to sync the browser with my phone, in case it clears all my passwords.

Hello, I have Windows 7 and I use Firefox ESR as my browser. It has work correctly for years now, but since a couple of days it has problems with downloading the latest updates. It asks me download the update but as I go into the settings page, the download is stuck at 0 kB. I also get a message box that FF is not able to download the update and it sends me to a Mozilla Firefox ESR download page and when I want to download the ESR version, FF cannot open the page with the installation file. Also many other links on the Mozilla page do not open or do not open correctly. Also it doesn't open this support page, I am writing this messages through my phone. Also it doesn't open the website bol.com. So what can I do. I have already tried clearing the cache and cookies. It doesn't help. I hope you can help.

On 2026-04-15 from about 10:00 CDT on, I have not been able to update Nightly nor Firefox Developer Edition (Aurora). Both of them notify me that there is an update available, and when I click on Help -> About Firefox I get the usual panel that gives me the update ID to click on. Clicking on it tells me it's Downloading Update -- 0 bytes, and it never flashes the expected size of the update, never shows progress, and never completes. It seems to be acting as if the update server is out of commission.

Firefox no longer allows me to delay updates. Twice in 2 weeks, all of my cookies were blown away during the Firefox installations of 150.0.0 and 150.0.1. I have 8 Google Email Accounts - all forgotten and no longer accessible. The same is true for Yahoo finance; banks; and the myriad of other sites I use daily. I checked this morning, and all sites visited before 150.0.1 was installed (against my will), have zero cookies. Only sites visited after the installation of 150.0.1 have cookies. This is a tiny subset of cookies I rely on for daily use.

This makes Firefox useless. I can't spend hours trying to recover from untested software every two weeks. Until this is fixed, I have to switch to Chrome or Edge.

I'm running Windows 11 Pro..

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes.

After I upgraded Firefox on my Dell desktop the left side of my keyboard stopped working so. I bought another keyboard when I upgraded again it stopped working. Talk about frustration

I'm trying to open a file that was sent to me, but my computer is asking me to update Firefox. When I try to do that, it shows that I already have the most current update.

A new issue with Firefox. I download updates myself, not automatically. This morning after updating, I clicked to restart Firefox, and it restarts, but still shows that it needs to restart. Even after multiple attempts. How to resolve? Thanks

I'm too old and tired to try to find my way around the new update. How can I return to the previous version? Life was so simple. Now I spend more time trying to find things that I can't find than I do online doing something productive.

Please tell me there's a simple way to get back to the previous version and that I won't lose my bookmarks and links.

I "create a new profile" days ago what I first received the notice to update. It seem to work except when I click on a url to view. I received instead the notice that I am in the old firefox and to "Update". I did again and it seem to work until I clicked a url to view and again received a notice to "update by creating a profile.

It's very frustrating - Now I can't open firefox at all. It wants me to "fix it" or create a new profile"

Help! All my bookmarks have disappeared from the Firefox browser. I believe there has been a browser update done by Firefox. I found various ways to recover bookmarks and found a folder named 'old Firefox Data' on my desktop. But all files I try to import give me an error message stating that this file doesn't contain any bookmark data. I tried to import bookmark files and favicons.sqlite files. No luck. I now cannot access bookmarks accumulated for about 10 years. Really need to get them back into this new browser. Any advice highly appreciated.

So I know this question has been asked and answered in various scenarios but so far I've not found one matching mine.

Personal PC. I'm on V 131.0.2 since a reinstall last year but only now realised no updates have been done since because of this msg. I've worked through the various fixes others used re policies, but I can't locate any policy files in the various locations suggested; registry editor (HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox key (don't have it) & others, about:config (nothing showing on a search), Program Files/Policies (don't have it), C:\Program Files\Mozilla Firefox\Distribution folder (don't have it). So I could not find the offending poicy DisableAppUpdate anywhere in locations offered by other posters etc.

Rather than taking forever to pin down the culprit, can I not just manually update to the latest version or will that delete all my settings/extensions etc?? Given how often it's crashing I'm almost tempted down that road except that I like to have my History intact as I often want to find a site I've not bookmarked.

Thanks.

After the 8/5/25 Firefox update the internet is inaccessible on my laptop through the standard Firefox browser. The internet is accessible with MS Edge. Toolbar is set to always show bookmarks but none appear. Also, the browser's application's menu does not open to access options such as restore previous session, recently closed tabs, etc. I've restarted my device several times without it resolving the issues with the standard browser.

The Firefox developer version opened in command prompt safe mode (firefox -safe-mode), which is how this inquiry is being sent, but no bookmarks on tool bar or current page history from the standard (non-developer) Firefox.

I'd like to return to accessing the internet using the standard Firefox version with its bookmarks, history, etc. I am using Windows 10. Thank you.

Ok so a month ago FF updated on four W11 laptops and now every time since then when you open FF it wants to make changes to your HDD and then tells you it can't download the latest version. I've uninstalled it and reinstalled it and its the same across all devices. None of the three devices are running any of the same software aside from the OS as they're all dedicated to different purposes, so I know its not something on the devices themselves. We ended up uninstalling it on everything aside from the older W10 desktop because its a constant nuisance. Each time it updates it is successful and there's no failure messages, so it's not like its obviously failing to update, but something certainly broke.
