Duplicate install of Firefox

more options

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.

Bumping, because this has now happened to me across 3 separate machines, so I can't really ignore it as a fluke anymore. Could it be because of my region, or something to do with my account, or......? Help would be appreciated, because I don't want to have my Firefox forget all its tabs and logins every other month. It's not like it's the end of the world, but it's quite annoying.

I wonder whether this could be related to the new profiles feature? Firefox's legacy profiles feature lists each profile individually on the page at about:profiles but the new one is accessed through the main menu instead. If you have not yet tried the new profiles feature, I suggest holding off on that until everything is sorted out.

Thanks for the response. I don't see the new profiles option yet, so I won't fiddle with it. I can however see two profiles in about:profiles, so I'll check those out. What do you think might cause a new profile to be created?

New profiles would normally only be created by Firefox if the old profile was inaccessible. However, Firefox might prompt you to allow it to create a new profile if it thought you had rolled back to an earlier version.

I don't know enough about the way Firefox is packed on Linux to know whether changing package types might also trigger creation of a different profile.
