Doesn't block anything, just redirects...

Doesn't block a lot of sites.

BlockSite njedzja bloockers

This extension is simply not working. I installed it just for blocking one page ¡just one! which appears constantly as a pop-up in another page that I use to visit. and it simply does not work. Even after restarting.
The deceptive page is deloton.com, in case you want to fix your extension.

This module does note work if you run a second instance of firefox

(Version 3.1.15) The time scheduling doesn't work! Please fix this.. This feature was the only reason that I needed this addon :(

Update: I found an app with the required feature: "Leech Block NG"

Frustrating. Can't get it to work and it has already eaten up an hour of my day trying to figure it out.

The timing feature doesn't work for me, sites remain blocked at all times even when I set a certain timeframe. Only reason I want this add-on is for the timing feature, if anyone knows one that does work please post the name of an alternative!

Seems to show only 1 address though 2 are set. Also, doe not work.

Was a good add-on, now it's crap that doesn't work.

Doesn't block links as promised; at least in my experience!

I got this to block http://dominion.games, but it just says "Incorrect URL". I hope you don't have a whitelist of TLDs..

It worked beautifully until the last update, now it blocks NOTHING! Very disappointing...

How much do you pay others to say it works? Doesn't work. No good. Used to work.

It does not work proper. Time settings don't work. Sites will be allways blocked! Mybe the test it agin and make a new release.

This add on doesnt block anything. total waste of 2 minutes to install. why release an add on that doesnt work? what do you get out of it? i can only assume these guys work for chrome and are trying to get people to switch browsers because firefox dont test add ons.

Not work anymore

One an easily bypass the block by opening an Incognito mode. What a poor implementation.

When I open second instance of firefox the sites are no longer blocked

It forgot which websites to block. How useful is that?

Used to be good.
I guess they sold out to advertisers.
Used to be able to add wildcards to block sites, now onky accepts specific addresses, which doesn't do s**t because spam changes address a bit automatically.
So pretty much useless now.

Doesn't work at all for me.
Maybe I'm doing something wrong - I enter the site, set the time for every day of the week and 00:02 until 0001 and it blocks absolutely zilch. what ever I try and whichever way I try.
