Rated 4 out of 5 stars

This addon is good but fading. More and more website are getting able to fight against it. Please keep updating it.

I'm sorry that I didn't be specific. It's adblocking. The adblocking ability seems weaker now than before. FF shows more ads than it used to with BHF.

Okay. These are some examples but they are all Chinese websites. Yet I don't know about ad networks. They just look more colorful and flashy or animated.

Thanks for you time and reply

This review is for a previous version of the add-on (2.1.1-signed). 

Thanks for the links. Well, i did a brief look and there are being blocked several resources on these sites, for example:

You can see there the browser console open with my debug-enabled build reporting everything which got blocked. However, on the right-bottom side of the page i can see a little advert there, that specific one is served by the site itself, something Bluhell doesn't take into account. Hopefully this bring you some light.
