This review is for a previous version of the add-on (1.2beta). 

Thanks for explaining how to get the fixed version. I keep trying, but people don't see it. Hopefully they will see this. I did just upload to beta3. Hopefully addons.mozilla.org approves it soon so people won't need to read this. (There was a small error in beta2 that threw errors into the error console, but worked correctly anyway - unlike the first beta)
