Impossible to use

Ne može da se otvore opcije sa Firefox Toolbar-a, a i kada blokira nešto otvori drugu stranicu a to je isto kao i da nije blokirao jer moram da zatvaram onda tu stranicu

works perfectly, and now, i am little more happy because i cannot access to news sites. so good

Works as advertised, but I wish that it synced with the android app.

eats up all the memory on the computer

Had been using this for the white list feature, and it had been working fine
Today I see that the white list mode had turned itself off, but more importantly the entire list of whitelisted sites has been deleted as if the add-on had been freshly installed.

Cooooool plugin!It makes me more dedicated on my job!

There are many headaches from simply trying to enjoy the online world. BlockSite is my first line of defence; thank you.

This is the only site blocker that works for me. Every time. All the time. Firefox.
