CloseReview for Expression Search / GMailUI by Darwin4Ever
Rated 5 out of 5 stars
There was no way to update to the newer gmailui-1.0-tb.xpi with the AddOn Updater (always gave a download-error) !
The good news is : after downloading the gmailui-1.0-tb.xpi manually / locally and installing (actually updating) from the saved file, it works in TB45
