User of Malwarebytes Premium, I'm not sure if this add-on is redundant but, hey! let's try!
I use Ublock0 + Umatrix and on some pages Malwarebytes seems to block things that are not blocked by those two tools. It would be a very good thing to add the possibility to see details of blocked resources.

EDIT: some false positives. Pages add-on detect as suspicious/malwares but are totally legit. The desktop application don't detect them and a search on virustotal give "all good" result. There is work to be done on the detection engine.

As a premium user of the desktop app I'm gonna stop using the Firefox add-on. Some measure of protection are already taken and I'm not interested in the functionality like "clickbait prevention" as long as I'm not a stupid user and know to use self judgement. Still in my collection, I will keep an eye on it.

However I think it could be a good add-on if you are not premium user of the desktop application.

Keep up the good work.
