Thanx so much. Now I can upgrade to 68. But I only found this because an sfhowes posted an answer to my request in the forum. I cannot figure out how to find it from scratch by searching in the Add Ons catalog. What is that?

This review is for a previous version of the add-on (2.1).

That's because it has not yet been reviewed by Mozilla.
Technically, this is not an upgrade, it is a new extension.
