New "feature" ??? Rated 5 out of 5 stars

I love this extension and have used it for years. However, the new (CTRL+SHIFT+Z) does absolutely nothing – although I'm more than happy to continue using the toolbar button.

This review is for a previous version of the add-on (1.0.8). 

New fixed version 1.0.9

Thank you Turtleman, i just added a new version. Please wait, until it has been reviewed by mozilla team. Because of internal usage of STRG+SHiFT+Z, i replaced the SHiFT key with an ALTernative key :)
