Good day, I'd like to start by thanking the Mozilla Firefox dev team for the newest iteration of the profiles feature. I think it's great. One area where I think it could use improvement from usability perspective is a way to launch a specific profile via the right-click menu when using the taskbar icon. Currently, using the "Choose a profile when Firefox opens" only gives users the option to select the profile on the initial launch of Firefox. After that if the user opens a new window via the taskbar, the most recently opened profile is automatically chosen. I managed to find a "hack" to add the requested capability. It seems adding an action to the "firefox.desktop" file in the "/usr/share/applications/" directory works the way I'd like it to. Modifications to "firefox.desktop" Changed line 12 to: Actions=choose-profile;new-window;new-private-window;open-profile-manager; Added lines 529 - 534 (before Desktop Action new-window): [Desktop Action choose-profile] Exec=firefox --new-instance Name=Choose Profile Name[en_US]=Choose Profile Name[en_CA]=Choose Profile Name[en_GB]=Choose Profile The end result is a new option available when right clicking the taskbar that opens the new profile selector. Screencaps of options before and after attached. I imagine that users will need to have the "Choose a profile when Firefox opens" enabled for this to work as expected, but would like someone from Mozilla to confirm this. Would like to request that this option be built into Firefox going forward, so there's no need for users to "tweak" it to get this functionality.
