I’ve been using Firefox on my Mac without any issues, but I recently had to erase and reset my Mac. After reinstalling Firefox and attempting to sign in to my account, I am unable to sync my data. When I click “Sign in” and enter my password, I successfully log in. However, it immediately returns to the message “Please sign in to reconnect,” and I am unable to proceed with syncing. This is the first time I’ve encountered this issue. On a positive note, I can still see my organized bookmarks on Firefox for iPhone, which were synced from my Mac before the reset.
