Works pretty well, but after a few years of using it my list of blocked sites just DISAPPEARED. This is when I was logged in to my FF account as usual. Bizarre.

Fantastic! Does exactly what it says and there's lots more under the hood. A pity it's not compatible with Firefox Mobile.

I want instant close option than minimum 1sec.

I use pages where I read headlines of articles I might click, but some pages are behind walls or I do not like - this is a nice protection. The contra is that a page opens with the restriction info, which I must close then - a 5 seconds blend in info would be more comfortable for me - luxury problem. :-)

It's nice to be able to block sites I don't want from loading, but I wish there was an option to have those sites instantly close, rather than having to wait the 1 second.

ottimo

Not working anymore
