Firefox Support Forum

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

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!

Firefox Installer.exe starts and, after some time, gives that error message: Ihr Profil "Firefox" kann nicht geladen werden. Es ist möglicherweise nicht vorhanden oder ein Zugriff ist nicht möglich.

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

As title- Cannot download for example webm format, but jpg is okay. cannot install any addon, theme or anything. DRM didnt install as well. i was trying reinstall, refreshing browser, rebooting.

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 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

I have had the option "Check for updates but let you choose to install them" selected for some time, because when FF auto-updates my system becomes unstable. Despite that version 126.0.1 (64-bit) was automatically installed. Which I only found out about because after causing FF to freeze, and basically crashing the work I was doing, and forcing me to kill the task with task manager, I get the "FF is installing your update and will start in a few minutes" at restart.

After looking thru the help forums I have set app.update.background.enabled and app.update.background.scheduling.enabled to false. (They were both true despite the setting selected.)

Two things:

1. I DO want to be notified when updates are available. I just don't want them to happen at your convenience. Will I still be notified of updates with these config parameters set to false?

2. If you have a setting that says "Don't Update" and I select that option, you should not update. There is clearly a problem somewhere.

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?
