Rated 1 out of 5 stars

Unfortunately, this is flawed in a manner that makes it unusable. When a site contains code to change the tab icon (to indicate a status change, for example), this extension prevents the tab from being updated. The old version did not have this flaw. Only toolbar and menu items that you set with it were affected. This add-on affects sites you never set it for. It's a shame someone hasn't simply done a straight port of the original.

This review is for a previous version of the add-on (0.4.0.5). 

the reason

if you read some of the early reviews, people complained about the toolbar icons not changing too - it honestly made no difference to me.
