Works just fine. However, I strongly dislike how it appears when one goes to a site one has blocked. It looks like you've been taken to some hack site. It would be MUCH BETTER if instead of the page heading being "Restricted Access" it said something like "This page/site has been block by the Block Site Firefox Addon."
Please, don't expect me to realize what is going on by seeing some stupid icon either. (I hate icons, but they're here to stay.) Secondly--although this may be an option--the screenshot shown in the example is white, while I get a BLACK screen (which, again, looks hackish).

Väga kasulik ja vajalik lisa. Väga hästi tehtud ja ilma probleemiteda

My kid just deleted the app extension, had password protection on and everything. Didnt even make it past 10 minutes.. sorely disappointed

There's no control panel(dashboard) with settings. How the hell am I suppose to use all those promised features??? Nobody knows.

Thank you very much! A solid website regulator. Probably the best in my personal usage.

Works pretty great, blocks the right sites as promoted.

He made a PERFECT change!!! THIS now does EXACTLY what I want it to do. I am totally thrilled with this; and this is tied first place with my most valuable tool! Thank you so much for making this!

not working

No agile settings. When I was disabled this addon, all blocked tabs has been closed. Do NOT close my tabs!
Furthermore, this addon continued working after I have deleted it and restart browser!
