STAY AWAY FROM THIS Rated 1 out of 5 stars

I Used this add-on earlier for some time.

Suddenly and without notice I got all kinds of lock-up problems without any change to computer.

A restore without this add-on (but with the other previous add-ons) is proof enough -> This thing is MALWARE.

Rated 5 out of 5 stars

I think it's really good.

This IS malware - steer clear! Rated 1 out of 5 stars

I can't speak to how well it blocks pages, but it litters pages (eg. Microsoft's support site, which does not have ads) with extra ads, opens pop-ups, and redirects searches and typed URLs to pages of its own choosing. Save yourself a lot of grief, and don't bother with this nuisance. I disabled the extension on a friend's machine, and Firefox once again became useable. Apparently, Wips.com extensions and apps also monitor and transmit info back to their servers on the pages you visit, so it is also a security/privacy threat - see http://www.ghacks.net/2013/01/13/how-companies-take-advantage-of-mozillas-addon-repository/ for example.

This add-on is so helpful, you have no idea how much. But I accidentally blocked Youtube and I can't unblock it - I don't know how or this add-on doesn't have the feature to unblock sites. PLEASE HELP ASAP

MALWARE BY ITSELF Rated 1 out of 5 stars

Beware this addon is a malware by itself. It does block sites in your list but it redirects you on ad websites randomly when you click on an url. Extension Defender reports it as a malware and it is true. I have no more problems since I deleted this junck.
Méfiez vous c'est un malware par lui même, je n'ai plus de problème depuis que je l'ai supprimé.

Just a suggestion: can you make it to actually block the tab? I mean now it's blocking only the site but the tab still opens. It's a half job, after a while I have 10 empty tabs opened.

It works for me Rated 4 out of 5 stars

Just installed on Firefox 31 and it works great.

Would it be possible in the future to make it automatically close blank tabs opened for blocked sites?

Appreciate the add-on.

sucked Rated 1 out of 5 stars

I specially logged back in here just to have a say about this crap app - its pops up a shitty reminder to say wtf its doing - when in actuality this addon is more annoying than the god damn ads themselves

Good - But could close the blocked site tab. Rated 3 out of 5 stars

Wips should ring an alarm bell. If you decide to try this out, we warned that Wips likes to configure their data collection as opt-out and hide the option. Do make sure you open about:config after installation, filter on wips and turn all *stats_permission* booleans off. I wouldn't bet on these settings being respected, though. You might be better off using a hosts file, be sure to include api.wips.com!

I would not recommend it until performance problems are fixed Rated 1 out of 5 stars

Using Block Site caused my memory usage to sky rocket to over 2.2 gig and my computer slowed to a snail's pace. I have left feedback for the developers. I hope they fix it because it sounds like a good idea.

Garbage Rated 1 out of 5 stars

It's a shame Mozilla hasn't banned the software for recording & downloading web activity without user knowledge and permission.

need icon Rated 3 out of 5 stars

It would be great if this addon had an icon on the menu bar or the addons bar with option to temporarily disable the addon. Otherwise it's a great addon.

This is the best url blocker for firefox.
Unfortunately is not perfect.
The biggest hassle is that blocking an url don't block the whole website and require manual review.

easy and the best

Useless Rated 1 out of 5 stars

I right-clicked on the site I wanted to block and it blocked it... as well as everything else. Only ONE SITE is on the blacklist so why the hell is everything else also being blocked??!!
