Incorrect sender names suddenly attaching to emails today

Thunderbird Send and receive email

A weird thing has started happening to my Thunderbird inbox in the last couple of days. Emails are showing as from a totally different sender. For example, a Google search on Sondheim has been "sent" by EDF (my electricity supplier) and some Groupon emails are showing as coming from people I correspond with. Also a Keto bread recipe from a low carb group I belong to has been "sent" by one of my work clients! More weirdly, I copied them into a subfolder on my inbox and they then appeared correctly. I have tried repairing the folder but it made no difference.

try disabling the use of "friendly" names in settings.

Search address and turn off Show only display name for people in my address book.

If that fixers it, you need to have a look as the email addresses associated with those names in your address book. The messed up ones are usually to be found in the collected address book.
