How to separate work/personal life on Firefox

Posted on — Nov 6, 2019

Two Firefox

I’m an avid Firefox user, both at work and in my personal life. As such I have some conflincting settings and addons. For example, I use the Lastpass addon in both contexts but since I use different accounts, I needed a way to get them to cohabitate. To cope with that, Firefox comes with profiles.

Firefox profiles?

Firefox comes with profiles, you can use them to isolate a set of settings/addons/plugins/bookmarks/…

You can have different profiles but you must set one as default. This default profile will be the one used when you start Firefox without setting a profile.

To open firefox with a different profile:

firefox -p ProfileName

This will start a new firefox instance with its own history/set of addons/settings etc.

Create a Desktop Entry for this new profile

We will need to create a new desktop entry. What I did is copying the one from Firefox and changing it to match my needs. You can find that file in /usr/share/applications/firefox.desktop.

We have different options that we will tweak there: Name, Generic Name and Exec.

In the end, your ~/.local/share/applications/firefox_perso.desktop should look like this:

[Desktop Entry]
Name=Firefox Personal
GenericName=Firefox Personal
Exec=firefox --class "Firefox Personal" -p Personal -no-remote %u
StartupWMClass=Firefox Personal

[Desktop Action new-personal-window]
Name=Open a New Window

That’s it!

Enjoy your separate Firefox instance. A tip: change your personal Firefox theme so to differentiate the two, I personnaly use Arc Dark Theme.
