Patience for how long? It has been over a month since release and more than a year since web extensions were announced and documented. Citing some obscure bug as the reason to justify 4-5 star votes against the shambolic way this has been "updated" and "is being worked on" (supposedly) is beyond convenient.

This is now a 1 star add-on, because that is the lowest rating possible. Forget the past, that doesn't matter now. Install it today and you can get weird colors like your graphics driver has messed up. If you really want to encourage or support the developer, then donate, do not rig the rating.
