Bitwarden is a very good service, though, its extension is not perfect or as good but it is good. I have rated it 4 stars but will rate it 5 if we are granted the ability to extend or collapse folders as we wish in the "My Vault" tab and not have to scroll past every single other login of all the other folders. (Btw it's little but it would be nice to "view" a login in the "tab" tab of the add-on when clicking on it's icon like in does in the "My Vault" tab.)

Other than that, I would very much like to see being able to set multiple URLs or android app URLs(?) to a single login. Moreover, it's less important but it still would be useful, the ability to create folders within folders like a filesystem. That would be nice.
I know this last two aren't more about the add-on than they are about the service in itself so it will not impact my review score.

EDIT: Hi, very nice change, it's great ! As promised I have changed my review score !
Now would you mind doing the same thing on the mobile app ?))
