Firefox Community Forum

I had the situation maybe a year ago. I use the Firefox profile manager.

I just updated to 127.02, and now not I'm getting this because for whatever reason, since the update, I am somehow on the beta channel, but only with this profile. I just opened two other profiles, and neither is on the beta channel, although i don't know what "Firefox is being updated by another instance" means.

I don't know if it's just a coincidence, but I'm also just noticing that a number of my addons settings have reverted to default.

Hello, I've installed Firefox twice in the last couple of days (Windows 10 - I think) and I continue to receive messages that say I need to install the latest version.

Do you issue updates daily, or is there something wrong with my Firefox installation or is it something else?

Thank you.

I started getting "can't load XPCOM" errors when starting Firefox. I did a full uninstall, then attempted to install the new version, I still get the same error during the install.

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

While following this step in order to reduce CPU and memory consumption of firefox [content-prefs.sqlite file], I accidently deleted the Profile folder itself.

After this firefox wasn't opening and was stuck on not responding in activity monitor.

I reinstalled firefox, multiple times even after a shutdown, removing any old files in the Library folder. Still it's stuck on the same issue, firefox doesn't opens up even once.

I cannot even download firefox because im getting an error message " cannot create temp archive folder" It wont even launch the install files. Something orgininally happened to firefox on my computer because i wasnt able to download anything with the browser download manager. I need help

trying to import login information from Firefox to Norton Password Manager. the Norton process works but no logins are displayed to import to NPM. There is a quick error screen when running Norton's import_password.exe - I would call a DOS window ERROR:root:extract_all_logins: Error for ALL: no profiles found

 Can you help?

I always had one version of Firefox installed. I regularly update the software via Help >> About Still, after every update, I am getting multiple versions of Firefox listed at [Settings/Installed Apps] and [Control Panel/Uninstall or remove apps] on my Win11 23H2 22631.3593 (screenshot attached).

In order to get rid of outdated items from the list, I need to reinstall Firefox completely, but the same thing is happening with every update of Firefox.

Is there a way to resolve this and why is this happening?

hello,when i download my attached files in mailbox(mail.xmvds.com), it can be everytime warnning me ,but i trust this url ,it is my company's office mailbox ,how can it unblock it ,?

Dear fellows,

I did lost all history data after a previous update, my user got corrupted data and somehow I did manage to import the info into Edge browser. To my surprise after I reinstalled a clean Firefox, it only imported back 3 months of browsing history. Topically, average user keep a computer 3-4 years.. I don't know from where developers came with the idea of limiting to such a shot interval. I have thousands of browsing history links from more that 10 years kept and I need them all.

Tried to increase the number from about:config, but there is an option only for Chrome which I never used and always hate :)

I did installed Chrome to convince myself about it's ingenuity, even if it was not necessary. It does have import option only from Microsoft Explorer, no Edge.

If there is a solution for importing a longer period and high number of entries, please share it.

I'm not an IT expert, but I can manage consoles if there is an even deeper option to modify config files.

Thank you in advance!

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

A firefox support article told me to reinstall firefox from snap on ubuntu, without mentioning anything about the profile, settings, and bookmarks. Now everything is gone.

Is there any way to recover my local profile?

I don't think it was synced properly with my other devices

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

MY Windows 11 laptop crashed and OS may need to be reinstalled. Will this wipe out my Firefox browser bookmarks. I would like to save the bookmarks somehow. How do I do this without access to that system?
