Very simple to use and does exactly as advertised. Thank You

Does what it promises, but source code is no where to be found despite the extension supposedly being released under the MPL2. Given the permissions granted to the extension it might not be the best idea to use it.

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Seems to be instable or out of date.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
