The dev has fixed the add-on which is now perfectly working.
I use it to prevent notifications and disturbing new messages mentions for newsletter filtered folders I have configured.

Tato recenze je pro předchozí verzi doplňku (1.0.4). 

I am sorry if the extension does not work for you. You can submit a detailed bug report on the github page, so it would be possible to investigate the problem and fix it for you and others. The next version, which is awaiting approval, has some more logging that can be enabled, so you can also wait for it to be released here to get more info.
