Rated 1 out of 5 stars

I've had to revert to 1.7.6.1, since the new version 1.7.7 doesn't work with Thunderbird 52.8.0 - it no longer switches properly between two profiles. I emailed a bug report to the author 3 weeks ago, but so far there's been no reply. So it's not clear whether this add-on is now essentially dead, or whether the author is intending it to work with the imminent Thunderbird 60 release.

Edit 2018-08-09: 1.7.7 still has the same problem with Thunderbird 60.0. Worse still, 1.7.6.1 doesn't work at all, even with strictCompatibility switched off. So this extension is now useless for me.

Edit 2019-10-07. Fortunately, the replacement version above by Dillinger works properly with TB 68.
