Like others say, you can't copy and paste a url into the blocker (when there's a page that hijacks and is an insanely long address, you are just hosed) and it doesn't actually do anything. The page you put the address into (adding manually) keeps popping up. Program is a non-starter in my book.

Nice

I can't get it to work....Needs to have copy and paste functionality and it needs TO WORK.

I tried it, but it simply does not work. Just takes up space...
Removing from my browser

Trying to block a website that keeps hijacking my legally blind sister's home page. This site puts up popups telling you to call a collect call number that then charges you hundreds of dollars a minute. The popups prevent you from opening a new tab, so you can close the homepage tab, so you can fix the homepage. It becomes a tug of war seeing if I can click on ESC and in that tenth of a second open a new tab, so I can hit ESC again and close the home page. So far, no luck in ANY of the site blockers..... seems it would be so simple

A simple, easy to use, light on CPU website blocker. It works well on the Nightly and Aurora update channel.
