Frustrated long term user Rated 1 out of 5 stars

This extension does not work far more often than it does, so as others note below, it is unreliable. And frustrating. And irritating. The dev's forum gives help suggestions that take too much time - like combing thru all installed extensions to find a potential conflict. Basically, the extension seems to be far too complicated, therefore it's easy for IT to conflict with other extensions. I give up, after multiple years of frustrated use.

This review is for a previous version of the add-on (7.0.3.5). 

You indicated you are aware of the support forum, but have you posted there requesting help?

I've also noticed from your other (mostly negative) reviews of other extensions that you are a user of the Firefox Nightlies. The Nightly releases are for testing purposes only and no extension should be expected to work flawlessly in that environment. Nonetheless, if you start a thread in the support forum, I'll do my best to help.
