Rated 1 out of 5 stars

I have been using Tab Mix Plus for many years. An update just took place, updating from version 0.3.8.3 (which worked) to version 0.3.8.4 (does not work). I wish that I could revert back to the older version.

This review is for a previous version of the add-on (0.3.8.4).  This user has other reviews of this add-on.
