You can type message to others on google hangout inside of thurnderbird, but you can't use the video chat option within thunderbird - It keeps asking you to install Google Hangout Plugin but you can't download the plugin inside of Mozilla Thunderbird. I tried download the plugin outside, but it still doesn't work. The sole reason I downloaded your add-on is because I need google hangout - but it only works 20%. Please fix issue.
This review is for a previous version of the add-on (5.0.0).
