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

I changed computers. I installed Firefox. I followed these directions:

Back up and restore information in Firefox profiles https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I copy the contents of the profile folder from the old computer to the new profile folder on the new computer. I opened Firefox and my bookmarks and Add-Ins were not restored. I manually imported my bookmarks from a backup and got them restored. How do I restore my Add-ins and all their settings and configuration files?

Why did that profile files restoration restore my bookmarks and Add-Ins?

Thanks to anybody who can help me.

Hello everyone,

I started using firefox actively a year back or something like that, last couple of months it started driving me nuts as it started updating every time I launch it, which is very annoying even if it takes only 10 15 seconds, I sometimes need to check something really quick and I have to wait for it to finish installing an update, even though I checked the setting for it to do so in the background, it seems to only do it after I launch it disrupting my workflow, which made me switch back to Chrome temporarily, is there a way to fix this?

For some reason, Firefox just stopped working yesterday. The only way I could get it to work again was to uninstall and reinstall (the refresh option did not work). However, now I've lost all my bookmarks, passwords and customization. I don't care about the customization and losing the bookmarks is an annoyance, but I'd REALLY like to get my passwords back. The installation created a folder of Old Firefox data, but when I open the folders that I think might be helpful, like bookmarkbackups, they are empty. Is there anywhere else I can look where these might have been saved? I did not have a Mozilla account so no profile until now which I just set up in order to access the forum. Thanks for any help you can provide.

I had downloaded a couple of pdfs from google drive via private browsing which were stored in my 'Downloads' folder. But as soon as I closed the window the pdfs were deleted. I had also downloaded a zip file which wasn't deleted.

Automatic update on my Windows 10 desktop of the the new update 127.0.1 resulted in a version of Firefox that worked more or less for some web sites but was unable to reach others.'

I recently installed firefox on a new computer and it will not access the internet. Any access request gets the message "Hmmm. We're having trouble finding that site." We cannot connect to the server.... It says to check that fiefox has permission to access the web, but I do not know how to do that. How can I get Firefox to access the web? I do not want to have to use different browser, but will switch unless this is resolved.

Fx 124.0

Why am I getting these notifications? I have the latest version, but this prompt not only asks me to update, but there's no mention that it will install the beta 125.0 beta 1

I have an older piece of equipment that I need to communicate with it and the 232 interface will only work through Firefox. I was told I can downgrade the current version to 3.0, which is what I need, but I cannot find out how. HELP

How do I download language data for translating on a machine that is not connected to the internet?

I already followed the instructions here to download an offline firefox installer: https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

and I downloaded the language packs I want here: https://releases.mozilla.org/pub/firefox/releases/124.0/win64/xpi/

and I followed the instructions here: https://support.mozilla.org/en-US/kb/deploying-firefox-language-packs

But translation still doesn't work. I even manually installed the "*.xpi" packs into the browser. I can see in Firefox's settings that it thinks the packs are installed, and it offers to translate pages it detects are in a different language, but translation fails. I noticed that the language packs are smaller than I would have expected - smaller than 1MB. Is there a way to download the language data that is needed for offline translations?

Thank you!

I'm using Ubuntu 24.04 and just reinstalled for unrelated reasons. I'm trying to copy my Firefox profile over from my backup to the new installation.

I used the Ubuntu Snap store to install Firefox and put my old profile in -- this is the one that I was using on my previous Ubuntu 24.04 installation just a couple days ago -- and everything seems fine, but I do see this error message:

[ERROR error_support::handling] suggest-unexpected: Error opening database: Incompatible database version: 18

It gets printed when I type things in the search bar, so it seems related to some sqlite database related to history and autocompletion.

Is there a way to fix this? I'm fine with just deleting it, so long as the other parts of the profile remain.

(This is a strange error, since after all I was using the exact same setup -- Firefox on Ubuntu 24.04, installed via snap -- just a couple days ago, and it was, as far as I know, up-to-date.)

I just got this new computer and want to transfer my FireFox bookmarks and history to it. I cannot access my old account because I do not have access to that email anymore, and you require me to get a code sent to that email to log in. That is still on my old computer that was originally running Windows 8, and has been deteriorating ever since Microsoft jammed Windows 10 down it's throat.

I might still be able to export the bookmarks if there is some way to do that.

The best way would be if I could access to that old account without needing to access bonin006@umn.edu my current email is wayne@nano-dyne.com

Please see if there is a way to help me.

Thanks, Wayne Bonin

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

I've followed this tutorial on howto install firefox as deb via apt. After successfull installation the menu font looks really wierd. It looks stretched and the numbers are not displayed correctly.

The left image shows snap package install and the right image deb package.

Ubuntu 23.10 Firefox beta

I'm using this instructions to move my profile from old laptop to new laptop. I've had success with this method in the past, but not today. I copied the files over to my new device, open FF on the new device, and FF just opens as a new installation. What is going wrong?? (I'm going from a Windows 10 laptop to new Windows 11 laptop. (Ugh, I already haaaaaate Windows 11, but that is for another forum!)

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.

I have all my passwords stored on Firefox on my macbook pro. When I follow the instructions to sync my passwords on the Firefox app on my phone, it keeps rejecting my primary password, saying it is incorrect. I have deleted the app and re-installed it on my phone, but it still does not work. Why will my account not open on my iphone app? Thank you!
