No more working Rated 5 out of 5 stars

Very usefull, absolutelly best plugin for me in this field. But latest versions are no more working... I found some old installation and all was fine until updated. The same is on Windows and Linux FireFox latest installations.

This review is for a previous version of the add-on (0.3.1-signed.1-signed). 

Try "apply to all tabs" in the setting window
