I remember when this worked a long time ago, it was a nice feature, allowing one less click to open gmail subfolders. Just saw it updated here and gave it a shot, and it does absolutely nothing. My tbird is always kept updated so I don't know if the extension needs updating or even worse if its a scam. I hope not. Either way I got used to not using it over the years. Uninstalling.
BTW I've used thunderbird for 20 years and love it.

Thunderbird's change to multiprocessing has stopped it working and I haven't yet been able to look at what I need to do to fix that.
