Interesting, does it continue if you do a re install?

Hi Matt, I assume you refer to a reinstall of Firefox? If so how does this help Thunderbird recover profiles?

NB I have found Thunderbird profiles - if these a re the missing ones - what to do next.

I have been using both Thunderbird and Firefox for many years and never encountered such a problem.

Best regards Graham
