Very useful

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.

Everything is lost after a restart. For some people it works for others it does not. I open multiple windows and profiles, I believe it cannot handle that.

Good looking, simple and easy to use add-on to block websites. The funny notes each time you get blocked makes it better.

But there 's a bug, it won't block the blocked site if you open it in new window.

Will update my review if there's any new necessary experience. Will give 5 stars for now.

Smart, beautiful and lovely design and functions)

Just by installing the extension and setting a specific blacklist rule in a new browser window, I could block a stupid-ass scammer website that denied me all access to my browser, without needing to close all tabs in my first browser window. Very nice!

Facil de usar y ofectiva

Doesn't do shit! I mean, it really is not working for even the simplest cases. What is this?

It has a very serious bug for the whitelist setting. It only works on the first window. It doesn't block ANYTHING when a new window is opened. That being said, everything work perfectly on the first window. Fix that bug then we can use it for our school computers. I need to only allow access to the URL(s) for our tests.

I would love it to be able to sync the blocklist.

It takes 1 full second after the site will be blocked. Its useless when sites redirect you.

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