easy, simple and doesn't eat my memory.
'Nuff said!

It used to allow wildcards.

lets me block exactly what I want and nothing else.

Much worse than previous releases. It does a very poor job blocking sites. I am looking for another blocker. It used to work but now very ineffective. Letting a lot of sites I thought I had blocked through. Wildcards are no longer allowed so all the offending site has to do is make a small change and it gets through.

BLOCKS ALMOST NOTHING!!!

Blocking in the new version for FF 57 does not work in many cases. E.g. I have this file blocked and yet it is loaded. Before all worked as expected.
apps.[removed].sk/[removed]/js/jquery-1.11.1.min.js

Old version was very useful, the new one is useless.

Good

If you open up a second firefox window then on this window the sites are not blocked anymore

It does the thing that I installed it to do: block sites. User interface is plain and simple, which I like.

basic and beautiful interface

The URLs in my Block-List always are destroyed by themselves. At least: It seems so to me. But - may be its the final proof of extraterrestrial life.
If the Blocklist is activatet the URLs come up inspite of it. Withput my activity. So I think by myself - is it a stupid joke - made by the MOZILLA-staff ?
The Blocklist-addon seems to me absolutely useless.
But - may be Im only a 60 years old idiot.......................................

works fine!

It doesn't work as it would work
It can block a url but not a domain
I mean,
I can block www.domain.com/page1.html
but not domain.com
I've tested domain.com*, domain.com/*, domain.com.*, etc and nthing to do
The previous version was working very well but this no, doesn't work

In theory a well-designed effective app. In practice, it clears my blocklist every time i close firefox, rendering it useless. Reimporting only reintroduces sites, no other settings. Giant waste of time unless the blocklist actually saves. Help?

So far it works great, but the Chrome extension is better, because it have the option to block specific words. Hopefully the devs add this in the near future

1. Doesn't allow me to edit a blocked site
2. I could do without the smart-a*s comments at the bottom of screen! What is the point!! If you want to keep count, fine, but there's no need for the smart-a*s cr*p.
The old app was great, I loved it; sometimes if it ain't broke don't fix it

do not working

Literally it is a useless extension, I say literally because it only "blocks" some sites and others do not, and sometimes it doesnt work either. And write "blocks" because it does not avoid the pop-up since it opens an annoying tab, that's why it's useless.

I have been using this extension for years but with the last big update they destroyed all the good work they had done years ago, luckily there is an alternative that I found that is similar to the previous one and functional (I recommend it before this)

I liked this addon
But i don't want even a second to be displayed
The website address also appear

Doesn't work at all in Firefox 57.0.4

- the new version is toooooooo slow
- the new interface is confusing
- does not block sites that already have listings
- Most of the time it does not let add url
Summing up: it's useless
