Here's how to set up Thunderbird to import Google Groups: In Thunderbird, go to the gContactSync menu THERE IS NO GCONTACTSYNC MENU Select Edit Accounts HOW DO YOU EDIT AN ACCOUNT IN A NON-EXISTENT MENU? Choose your account WHICH ACCOUNT THAT ISN'T A MAIL ACCOUNT?
To be fair, those instructions do say that they are AI Generated. Which may well be why they seem so screwed up
(oh, and I am still using ggroups, so I cant reply to posts!)
