Blank Page Rated 4 out of 5 stars
nice idea. like having all my communication in one window. but since update to thunderbird 10.0.2 opening a google+ tab shows a blank page.
this is the same with using the webapp tabs 2.0 add-on so i suspect it is a problem at the google+ with regards to rendering in thunderbird (same issue with thunderbrowse 3.8 installed) and not an issue with the add-on developers.
