TbSync Manager

Rated 5 out of 5 stars

It's one of the most important addons for me in terms of multi-platform productivity.

90% of synchronisation is (or better: was) working smoothly, sometimes it needed to manual pull / re-activate the synchronisation. But overall great work.

Only: It is not (yet) working with TB150. I know it's the problematic update policy of Thunderbird, but is there any way or attempt to make it work with newer TB-versions, soon?

I tried to install the most recent version from github, but no luck - TB is saying it can't be installed due to compatibility issues. Also tried the workaround by don_pepe below to change the max version to 150 in the manifest.json, but no luck ("addon file seems to be corrupted").

Happy about any workaround!
