Thunderbird Really, Really Slow?

We’ve seen a few instances lately where Thunderbird has gotten really, really slow on a Mac. We’re not sure if this is a Mac-only problem, so we offer this solution up to anyone who experiences unbearably slow performance in Thunderbird:

  1. In Thunderbird, select Help–>Restart with Add-ons Disabled.
  2. Click “Restart” when prompted.
  3. When it restarts you will have some options presented to you. Check the “Disable all Add-ons” box, and then click on “Make Changes and Restart.”

That should fix it, but if not please feel free to reach out to us at helpdesk@hampshire.edu or 413.559.5418.
