Some stupid program has installed the version 78.0.1 (32-bit) of Thunderbird on my computer. My fault, I know. That happened on the 20th of July. Today e-mails I've received are not displaying when I click on them. I can see the contents however by, say, replying to them. Any idea what is happening here? Is there something I can do - like back-peddling to the current "normal" version i.e. 68.6.0 or am I stuck until a 78.something "official" version is available? Thanks!

Kaspersky Internet Security has a function called Software Updater which looks for updates to apps you have installed, and updates them for you unless you turn it off. Do you use Kaspersky?


Please try this: In Thunderbird

  • Help > Troubleshooting Information
  • click on 'Open Folder' button

a new window opens showing contents of profile name folder

  • Exit Thunderbird now.
  • Delete this file : xulstore.json

Start Thunderbird.

Please report back on results.

You're evidently a miracle worker! Yes that worked!! Could you possibly give me an idea why it worked?Kaspersky isn't to blame. The updater was IObit Software Updater and I played the role of the idiot. So yes, the moral of the story is beware of software updaters! Thanks a 1,000,000.
