Installed it, but when I try to use it, it tells me to log in, I click it, it opens a new tab and logs in, but then when I go back to Gmail, it is still not logged in.

UPDATE: It seems it does not play well with Firefox Containers. After some finagling, turning then on and off, login in and out, I got it to log in (but am afraid to ever log out now).

Seems to be working now. It'd be nicer if it worked as a pop-up with a wizard that would close itself and paste in email, but it has been working well.

Upgrading review

PS: Meeting subject could default to something better, like name of person who email is being sent to, or subject of email.
