Rated 4 out of 5 stars
Very useful add-on that is easy to use. Default time-out is too short however. The default appearance is also too invasive, with the toolbar respawning and un-hiding itself when the add-on is updated. Not sure why an add-on needs a "power button", but it should be located in the Firefox context menu or toolbar so that the add-on's tool and status bars are not seen when the add-on is "off". Finally, an add-on this powerful tends to meld into users' lives and needs to be kept up to date!This review is for a previous version of the add-on (126.96.36.199).
