Firefox Community Forum

Hello all!

I've started having an issue in the last few days, with apparently two separate Firefox installs. A few days ago I was greeted by a fresh, blank install of Firefox and had to set everything up and sign in as I usually would on a fresh system install. Today, however, I somehow managed to launch both of them at once (I don't know how, as I just use the UI shortcut). After closing both fully, I can now only start the "old" one via the shortcut.

OS: Bluefin / Fedora 42.20, Gnome 48.6

According to the list of flatpaks, only one is installed. Unfortunately that's roughly where my knowledge of Linux ends, so I can't troubleshoot this further. Help will be apprecciated, as I don't want to roll a die on which of these will start up every time I reboot.

When attempting install firefox on linux using the recommended install method (in order to use 1password fully i cannot install it via snap) the priority does not change from 500 to 1000 using the parameters described in the install guide. Here is an image showing my issue.

I noticed when I went to check for updates the Fire Fox Browser is, Windows MSIX Package Mozilla, MSIX 1.0 143.0.1 (64 bit). What is this and why? Do I need to uninstall this version of Fire Fox and reinstall a new one? If so, how do I do that without loosing all my data. Thanks for your help!

Just bought a Chromebook and was surprised to find that only the phone version of Firefox is available for use on Chrome laptops. Any timeline for a laptop version of Firefox for Chrome?

I think when Mozilla was formed, it received all the assets of the former Netscape Communications corp, yes?

I tinker with some VMs running vintage OSes, including DOS+Win 3.1, and Linux distro releases from the 90's and early 2000's. I'd like to, for example install Netscape 1.x or 2.x on Win 3.1 and Debian Hamm 2.0.

I am wondering if Mozilla has a download archive somewhere with historic releases like Netscape 1.x through 4.x for all platform for which builds were originally released?

I have been having trouble with my Windows 11 laptop. In my efforts to resolve these issues I noticed that I now have two installs of Firefox in my Control Panel. Both installed during my time of dealing with my Windows issue. Five days apart Feb 5 and 10, 2026. Both show the same version number 147.0.3, and same size 322MB. I have used FF for many years so these seem to have been installed sometime during my efforts to repair Windows. My FF was never a part of the Windows issue AFAIK.

Anyway I have FF working as I like with my Session Manager and various AddOns and personal settings, so I do not want to have to start over with FF. So how do I choose which instance of FF to uninstall in Control Panel?

My issue with Windows was my Outlook would not connect to the server. I assume Microsoft Exchange server, my internet connectivity was fine. And FF was fne as well. I eventually was able to repair my M365 connectivity. Major PITA from out of nowhere.

I'm trying to install Firefox to my 2012 Asus u57a laptop from a SD card that is in my phone cause the Internet explorer is outdated cause it is on Windows 7 and I am trying to get Windows 10
