but if sometime dont work very well it almost block everthing(like google reacpcha or even base doman).so it should have option to exclude url

Interesting results. I might flesh out this review at a later date.

A side note, for anyone who is concerned about source code:

Extension source viewer
https://addons.mozilla.org/addon/crxviewer/

Version 0.4 cannot be installed here (FF complains about it being corrupted).
Version 0.3.1 installed fine, but the provided test page indicates that it isn't working - page always tries to load the scripts.

Tested on XP SP3 with Firefox 48 (that's the latest one compatibble with my CPU, so don't tell me to update it, please)

Very useful, especially for ISPs that lot's of websites are unreachable.

Blocked BBC videos from playing. I couldn't see how to get them to play so I removed the add-on, all is well again. Shame it didn't work.

I'm all for this add-on but I appreciate links to source code so I know what I'm downloading.
