Does not block groups of websites, so the browser slows down to some halt. Darn.

Doesn't block anything at all. Not on adding element and not after page reload. For those who want add-on that actually blocking elements on page use ABP, it doesn't have block dialogue on 100% of whole internet, but for those elements that have dialogue it works and blocking em instantly.

very nice

does what it's supposed to

Schedule doesn`t work, so functional isn`t complete.

Excelente extensión

Simple, does what it says.

Works great. The only problem I have with it, however, is the localization (Spanish, in my case). As a translator it pains me having to use the terrible, terrible Spanish localization and I'd rather use a properly written English version than deal with this. Sometimes it's so bad it becomes unintelligible and it interferes with proper usage. I think this would be easily solved adding a language option in the settings tab.

perfect , works great

does not work

Very easy to use. Perfect for those who are addict to some sites.

THE BEST

Doesn't work...

I think it's going to be much perfect with the keyword block

Versatile and performs as stated. Some annoyances such auto-filling in the URL with http:// when manually adding URLs. And some domains are treated as invalid URLs so cannot be blocked e.g. market.space.

I can block disgusting websites from my computer. I love that!
Thank you

Was noch Wünschenswert wäre:
- Die Möglichkeit geblockte Seiten in bestimmte Kategorien einzuordnen. (z.B.: Werbung; Privat; Sonstiges)
Diese übergeordneten Ordner könnten dann individuell angepasst werden, wodurch es wesentlich benutzerfreundlicher werden würde.

Was man beheben sollte:
- Wenn Firefox ein weiteres mal geöffnet wird, so kann man auf diesem zweiten Fenster alle blockierten Seiten öffnen

What else would be desirable:
- The ability to place blocked pages in certain categories. (eg: advertising, private, other)
These parent folders could then be customized to make it much more user-friendly.

What to fix:
- If Firefox is opened again, you can open all blocked pages on this second window

Molto utile per il suo scopo
