How do I launch the Profile Manager of Flatpak Firefox with Gnome 3?
I would like the Firefox profile manager to open when I run Firefox from the GNOME 3 menu, be it the DashBar or the native menu. I installed Firefox using Flatpak.
I know that I can run it from the terminal with flatpak run org.mozilla.firefox -p. But how do I modify the .desktop file? I guess it is the one in /var/lib/flatpak/exports/share/applications/org.mozilla.firefox.desktop? I tried replacing the line
<span style="color:#323232;">[Desktop Entry]
</span><span style="color:#323232;">Exec=/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=firefox --file-forwarding org.mozilla.firefox @@u %u @@
</span>
with
<span style="color:#323232;">[Desktop Entry]
</span><span style="color:#323232;">Exec=/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=firefox org.mozilla.firefox --ProfileManager
</span>
but I cannot save the document because of “too many symbolic links”.
What is the secret?
I really wish Firefox would simply offer this as an option in its settings.
