Here's an easy way to handle multiple Firefox profiles on Linux
>On my system, I wanted Firefox profiles to feel like their own browser instances. Meaning, their own app icons and to not be grouped together. Almost like how it is on MacOS.
>
>
>
>To do this, I had to make multiple .desktop files. Here are the contents of that file. This targets flatpak, but it should work for traditional Firefox installs too.
>
>I called this profile "Personal". Note that this says ``--profile "/home/USERNAME/.var/app/org.mozilla.firefox/config/mozilla/firefox/personal"``. In this, "personal" is a symlink to the real profile folder name located in the same directory.
