Firefox Support Forum

I've copied the root profile folder from my old machine, created a new profile running Nightly, put the contents of old profile into just created one, and it just worked. Doing the exact same steps with Dev version doesn't work - app refuses to launch after picking imported profile as default one. Could it be because Dev has a lower app version?

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

Suddenly I cannot open my msn.com email service. I just get a blank page. I opened Chrome and the email opened promptly. Could it have become Blocked...if so, where would the list be, OR where can I check to see if that is the case. All other tabs open just fine

I can't download anything anymore. I get the "failed" message. I see in support questons that this has been going on for a long time even though there have been repeated "fixes" reported. I've used Firefox for a long time and really prefer it, but I'm having to change to Chrome to be able to complete my work.

Hello,

I made a download 10 months ago, it failed OK.

But every other week that same old download keeps on restarting and failing.. its some kindof bug.

It then piles up with all failed downloads from the last year and they all try to load again and again automatically.

I tried to reinstall firefox and all but its a weird bug.

I have screenshots if needed.

Best regards

Alex

My update preference for Firefox is to download but I will install it. But it consistenly (over the last numerous updates) changes it to Automatic. I do not want Automatic updates. I want to control when it updates. I do not see this issue addressed anywhere. I have checked numerous times. Please help! My sincere thank you for your time and attention to my request for help. Sincerely, Nicolas

Hi, my 2008 Mac Pro uses OS X El Capitan, version 10.11.6 and I am on Firefox 78.15.0esr, I cannot install the new upgrade. Can I continue using the older version of Firefox even though the sync will not work anymore?

I have been using Firefox for quite some time. Suddenly it stopped working on my computer, I tried uninstalling and reinstalling, but I keep getting a message that there is a problem with the download and installation. Can anyone help? Let me know if you need any further information. Thank you in advance.

I have been using Firefox for ages and never had a problem - love it - but now I see the remark: Firefox has ended support for Windows 8 and Vista on my screen at the right top corner. It also will no longer update my computer.

I do have and use Windows 10 - so I don't see what is the problem? I tried to refresh and that didn't work either.

Please help because I like to stay with Firefox but I do need to update and keep my computer secure.

I am not very computer savy so please tell me what to do in simple word.

Thank you for your help Christine
