Excellent but has a bug and some features missing Rated 1 out of 5 stars

I wanted to add a "checkmark" symbol to bookmarks that are OK and this Add-on is the only one working perfectly.
Excellent work!

But this Add-on also has a bug: the tabs do no longer show the website icon

Additionally, some features should be added.
- add also a user-defined icon to folders (so I can mark a folder as OK)
- allow to reset the user defined icon for multiple bookmarks at once (so if I have finished my bookmarks I can delete the checkmark and show the original favicons)
In the bookmark library I can select multiple bookmarks and edit the preferences for all bookmarks, so here you should also show your buttons to reset and delete.
