Rated 3 out of 5 stars

Version 5.6 shows as incompatible after updating to 139.0.2 (Mac). Can you please update for 139? Version info says 5.6 set to maximum 136.*. Per previous response, I am always connected to the internet and have this addon set to update automatically. Updated, this is definitely a 5-star addon.

Update or install from inside Thunderbird.
Don't download and then install from disk, that won't work due to addons like this requiring a max version on upload.
If nothing works send me an email and I'll send you a bumped version.
