I have downloaded and installed Thunderbird v 128.7. I can't find an extension or procedure to sync the contacts with google contacts. The Calendar did sync just fine. I tried to install the "gContactsSync" extension, but it says that it does not work with my version of TB (128.7). I tried to do the same with the "google contact sync" extension, but it gives the same error. Anyone got any idea of what will work for veersion 128.7 of TB?
