Works Great! Thank you. Any chance of making the Contact Tabs plugin work with Thunderbird 68.4.1 ?

The developer, speedball2001, says he is not planning on updating the plugin to be compatible with TB 68.4.1

This review is for a previous version of the add-on (2.0). 

Thanks for the review.
For changes to compact tabs you have to ask the maintainer speedball2001, if this is possible.
