Installed it... frustrated by: a) didn't work, b) no toolbar icon to make it easy to register blocked sites, but... see a)

Seems to be instable or out of date. It works for a few days and then id does nothing more. Epic fail

good add-on. It would be nice to have a whitelist , i.e. denying a domain, but allowing certain pages or sub-structures . E.g. deny facebook.com but allow facebook.com/user/*

Please add import/export site list

This is nos serious. Even after having been asked to add the possibility to import and export a list of the blocked sites about three years ago, people did not get the developer attention did not. I changed.

Great, simple addon, works as advertised. This addon actually blocked the requests to the site, like I wanted. Another addon with the exact same name just visually blocked the site but loaded it anyway - useless!

Works great on the desktop browser. Don't work at all on a mobile browser

It works perfect, it help me a lot to block those annoying pages, it would be great if you could export/import the block list

Questo è il miglio BLOCKSITE che io abbia mai usato!
