Since the firefox upgrade of March 4, 2026, I have lost all of my old emails in my inbox. These are important items I need to work on before I complete and file away. I need to gain access to them ASAP. Thank you.

I guess that your issue is a Thunderbird problem and has nothing to do with Firefox. How is your email account set up, as a POP or IMAP account? Did you activate Thunderbird's Quick Filter toolbar? Did you set up this same email account on another device (PC, smartphone)? Do you have a backup copy of your Thunderbird profile?

You recently updated to version 148?
