One Firefox working the other not Rated 4 out of 5 stars

@Sirhc

Thanks, that works for one of my Firefox browsers but it was totally unnecessary for my other one. Both are Sandboxed separately and the script you mention after editing in the none working one made the FF WebMail work. In the other Sandboxed browser the script is as the original and that is still checking gmail successfully so this might start to explain why the developer missed this. The working browser with the unaltered script has only one gmail account setup whereas the other browser which required the script to be altered had many gmail accounts plus a few hotmail.

This review is for a previous version of the add-on (2.7.10.1-signed).
