cannot seem to send emails to multiple people without going thru mail merge. I can no longer type the persons name in to: field and it will not autofill. I tried to go to calendar function and got a blank screen.

Can I go back to a previous version?

I use a number of add-ons that greatly enhance Thunderbird but they keep breaking as new updates are released:

Cardbook is a very useful address book add-on, integrating with my Google address book. However a few months ago it stopped working when a Thunderbird update was automatically installed (I think it was V158). The only way of overcoming this was to revert back to the ESR (Extended Support Release). That wasn't compatible with the database that had been modified by the latest release. Fortunately I had a back-up copy of the previous database which I had to recover.

A couple of months ago a new release stopped Cardbook working. By trial and error I discovered that Cardbook had been updated for compatibility with the latest Thunderbird release so I was able to restore normal operation by updating to Thunderbird V158.

Now Thunderbird has updated to V159 and Cardbook has stopped working again. If I open Cardbook it shows the address book completely empty. The Add-on Manager doesn't flag any compatibility issues. This is disasterous for me as I am totally dependent on using Cardbook.

Lightning Calendar Tabs is another useful add-on, giving access to my Google Calendar through a icon in the task bar. However that has also stopped working under V159. The Add-on Manager shows it as being incompatible with V159.

So why does Mozilla keep releasing updates that stop add-ons from working?. Can I revert back to V158 and stop further updates?
