It's great that the new 2.0.12 has fixed the cert popup issue. Thank you to the developers. Just however, 2.0.12 also introduces a new bug that in the "Details" of "Clear Recent History", only "Browsing and Download History" is there visible with all other items disappearing.

This review is for a previous version of the add-on (2.0.10.1-signed). 

Are you sure this is caused by the CertPatrol update? This works for me fine just like before and nothing changed in that part of the code in 2.0.12.

Check if disabling the addon or installing the previous version fixes it.
