Firefox Community Forum

There is a document produced by Mozilla Support entitled Install Firefox on Linux. There are tow commands explicitly for Trixie. They both start with cat <<eof. the first one didn't work and was obviously incorrect. after much digging i found that wrapping piece eof like this 'eof' works. did not figure out, someone else did. hope mozilla support will update file. < p></eof.>

How do I install a PREVIOUS version of Firefox? I had version 149, and it auto updated on the 7'th. After that update, the problem began. The problem is, something in that update broke google maps as it's used on Realtor.com. It's impossible to drag the map with the mouse, I can zoom in or out with the scroll wheel, but then the area I want to look at is off the screen and I can't drag it back into view.

I downloaded version 149.0 and closed Firefox and tried to install it. BUT it starts, says it's checking space requirements and such, then the installer just stops... because version 149.0.2 is installed. I don't want to uninstall it because that'll wipe out all the settings I have and I'll have to redo every da*** thing from scratch.

I don't have time to wait weeks, months or years for enough people to report this bug and then developers fix the bug and roll out an update for it. I need to fix it now, tonight. And the only way I know to do that is to install the previous WORKING version of it.

Could someone please tell me how to force the installer to install version 149.0 WITHOUT having to uninstall version 149.0.2 and then having to redo every fricking thing...

The developers really should have a ROLLBACK utility in the Settings so that when something in an update breaks the functionality, all a user has to do is click the ROLLBACK button and boom, it reinstalls the previous version without having to jump through hoops to do it.

I do not have this problem in Chrome or any other browser, it's specific to Firefox. I do not like using Chrome or the other browsers I have. I much prefer to use Firefox. Someone please help with this, please!

I am running Firefox on Kubuntu, which means it comes pre-installed as a Flatpak.

I was having problems with various web sites so I decided to try using the version of Firefox installed with the file found here - https://www.firefox.com/en-US/thanks/

There were no problems with the install. This version of Firefox showed the same issues as the Flatpak version, so I blame the web sites.

Now I have two versions of Firefox. I would like to remove this second version but all the methods I've found do not remove it. I can certainly disable it by renaming the directory created in my user directory /Firefox. Trouble is, shortcuts I created to web sites always launch this version rather than the Flatpak version and I can't find a way to get the shortcuts to use the Flatpak version.

Previously when installing Firefox, it used to create desktop shortcut for All users: C:\Users\Public\Desktop

Now it creates in user profile: C:\Users\UserName\Desktop

I think the first option was better for systems that have multiple user profiles.

I have always downloaded and used the beta version of Firefox on both my Windows 11 and Android environments. Recently I've noticed I'm no longer using the beta version on Windows 11, but am so far unable to find a download for it, either from the Windows Store or Mozilla itself. Can anyone tell me if it's still possible for members of the public to install Firefox beta on Windows 11 platforms, if so how, and if not, why not?

I had a version of Firefox after March 20 that was BAD due to a scam that I got and did not recognize it. After the 20th my email was used to send a bad change to Firefox and I can't get anything to work. I needed to change my email password to halt the persons that were being sent the scam. I need to a have a version of Firefox to install to remove the bad dlls from the scammer which were on the Firefox that was comprimised. My old Firefox (before March 20th 2026) was working fine Can you help?
