Browsers (242 programs)

Pros: Free to play game with optional donations. Very addictive 'one more try' gameplay.

Cons: Very focused game with nothing else to offer. May be unplayable for those with colour blindness.

Pros: Easy to configure. Allows you to block sites between various time periods. Allows you to configure password access to sites.

Cons: Will not stop you if you are determined to visit a site. No substitute for self discipline. Still allows Firefox to reveal your IP address to blocked sites.
