Feature Requests and Bug Rated 5 out of 5 stars

Now, with the improvements of the version 3, this extension is almost perfect.
I've only a feature to request: double left click to "fast reset" zoom (that is... return to 100% zoom).

Another little feature request: improve graphics of the addons bar icon (especially, avoid the compact mode increase the height of the addons bar).

Perhaps a BUG:
When I use popup menu to choose the zoom factor, it is changed but not memorized, so the next time I open the page, the zoom factor is the previous choosen using + and - buttons.

This review is for a previous version of the add-on (3.0). 

Fast Reset

Thanks for your comments. There is a feature to "fast reset" the zoom level to the default zoom level -- just middle-click on the percentage (this works whether or not left-click reset is enabled in options).
