kinda baffled this exists 4 days after i even thought about looking into it, So far it's not giving me the correct links that i add to my new shortcut(only gives me a stupid long url that just links to this site), nor does it effect my current bookmarks but this is a much needed addon so i wish you the best and look forward to future updates.

PS: I got this for my Github bookmark because i use a theme extension that changes the theme depending on the contents, My start page though is dark and thus I cannot see the Github icon and i don't have a label on it.
