Firefox Support Forum

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.

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

Hi folks,

I'd like to obtain some clarity on provenance aspects of Firefox released as a Flatpak.

I see in this article that one of the options is to use flatpak package: https://support.mozilla.org/en-US/kb/install-firefox-linux

Is this article produced / reviewed by mozilla? Is flatpak an officially trusted, backed by mozilla, means of installing firefox on a system?

On flathub one can observe the "Verified" seal which indicates that such package is developed and maintained by original package developers (in case Mozilla). One can also observe in multiple forums here and there that mozilla is the one that builds and maintain this package.

Though a seal is nice, and users opinions are ok, it would be good to have artifacts that would evidence better this relationship. Also, would be good to have this officially stated in mozilla's website, under "Download options and other languages" section, something like "you can also safely install firefox through the flatpak package available on flathub which is developed / maintained / signed by mozilla itself".

Or maybe all of this information is around and i am just not able to link it together.

Thanks

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.

Ive tried reinstalling firefox because i am not able to download anything with this browser. I thought freshly installing firefox would fix the issue and allow me to download but it didnt. I also am tried to download an addon/extension, and that automatically fails to download. How can i fix this?

I have been trying to solve this for a few days now. I tried to watch Netflix when it said, "Firefox is installing components needed to play the audio or video on this page. Please try again later."

I found out this was due to Widevine not being installed AT ALL on my browser for some reason. The plugins manager has been saying that it will "be installed shortly" for a week now. I already tried toggling DRM off and on multiple times. I already tried using troubleshooting mode. I already checked GMP preferences to make sure nothing relating to Widevine was set to 'false'. I already tried turning off my antivirus long enough to try everything again and still nothing has changed. I do not have any VPNs running either. I am attaching a screenshot of what the browser console shows when I toggle DRM off and on again and try to run Netflix. I am also attaching what the gmp toggles say. Please help me figure out what is wrong!

Hi, I keep getting this error when I try to download any extension. I also get an automatic download fail as soon as I try to download anything. I have tried several solutions such as changing privileges to reinstalling firefox entirely. I have checked other browsers on my computer and it is just firefox.

I have Firefox 126.0.1 installed yet get a notification daily asking me to install the latest update When I down load the "latest update" I get Firefox 126.0.1 ! How can I stop this annoyance? Thank you John

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!

i need some help with my firefox browser. all of a sudden my firefox browser wont download any files from anywhere but if i try to use the save image as on an image firefox would download them. weirdest thing is other browsers are fine when downloading files.

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 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.

Edition Windows 10 Home Version 22H2 Installed on ‎2024-‎04-‎09 OS build 19045.4412 Experience Windows Feature Experience Pack 1000.19056.1000.0

(Windows reinstall via Microsoft's cloud reset "save my data" option specified... though some stuff got wiped out due to hard drive issues)

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?

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
