Add better customization to favs icon

Is your feature request related to a problem? Please describe.
There's planty of times i wanted to modify an icon because of copyright or the picture is not squared so it's strech things and stuff like that...

Describe the solution you'd like
( Firefox user ) I'm someone who love to change everything in customization. Icon in Bonjourr is ok but same that firefox, limited...
I would love to see a button named "Browse / Choose / or something.. " and to see it when we double click a fav just below "save" or somewhere else i don't know. The possibility to browse in our folder not only links :)

Would be awesome :D

Hello @Avenmic!

Adding local files for quick links is not planned for now, but some people have been asking for it so we'll keep that in mind 🤙
