FF 22.0 Rated 2 out of 5 stars

Doesn't work for FF 22.0!

Rated 5 out of 5 stars

The very good idea, but we need an ability to toggle on/off this extension globally. And the toolbar button should visually show the on/off state of the extension. After that I give you 5+ points ;-)

Update: Ok, your extension is very useful. 5 stars! :-)
Some tips for the future: the toolbar button should display the status of the extension even when there are no previous pages to control the state from any page and a state of a browser. 2nd: I don't know why, but FireFox (3.6.23) reload previous pages instead of to load they from the cache.

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

i added a disabled icon for it, when you click the toolbar button then that should disable it globally
