OK app but buggy distrib Rated 2 out of 5 stars

I had to download the .xpi provided in a user review (Mint's, from Sep 15, 2012). The link from firefox doesn't work (login failure) and caused me to waste a lot of time trying to define a new profile.
In the past I've had opportunity to use an older version; and I basically liked the way it worked, even if I had to update the .xpi manually to make it accept recent versions of FF.
So there's a recurrent distrib problem with this app.

And I've now had opportunity to see that the latest version doesn't properly handle Google multiple accounts (logging in to one account sometimes kicks me out of another). So I'm going to install Gmail Watcher instead. It doesn't do automatic logging; but does well what it claims to do.
