FF 34+ Rated 5 out of 5 stars
Indispensable addon. With Firefox 34 it stopped working. Additional functionality in the context menu and address bar are not working. I sent a report on the problem via mail some time ago (tested with the Aurora releases) but no reaction. Hopefully the project is not abandoned.
Non-working for now. Otherwise 5/5 stars.
Tipp for all with the current problem: When you reset the settings at least the shortcuts in the address bar starts working again.
