Used Thunderbird happily for many years to read my Gmail account but a couple of years ago I had to replace my laptop. Thunderbird stopped working, returning the profile missing or inaccessible error. I have used Web-based Gmail since, but I miss Thunderbird, which I still support! Just downloaded the latest version but it makes no difference. Is there a solution? I'm no whizz, but my husband could help, if instructions require more expertise than I have. Thanks!
