09 June 2019 - This extenstion has started breaking down fb page. With this extenstion installed and enabled, and both modes on, I can't post comments on FB. I then starten ff in safe mode disabled-enabled all extensions one by one, finding that only this extension disabled removes that problem, so this is the culprit.

couldn't find any kind of link here, to go to its website and post bug there, hence had to post here.

previous review - Why doesn't it offer "enable" and/ or "absolute" as a default for all sites? it is sort of helping sites in principle to block normal browser tools. bad policy. thanks.
