Misleading sites, black-hat SEO sites, and annoying mirrors sites are no more.

By the way, if you somehow find that the setting doesn't work, ie. the "Hide the 'Block this site' links" in Google, at version 8.1.0 in Firefox 105, you just uninstall then reinstall it again.

*Note: Forget it. Turn out it just broken. Uninstall then reinstall just temporary fix, because after a few hours it just broken again. Maybe I should report it instead.

wonderful add on. really helps control the awful experience on search engines because of content farms. also use on firefox android (iceraven) even though the full compatibility isnt available yet. active developer. brill!!!!

Overall it works great on Firefox 91esr! However it is incompatible with older versions of Firefox, such as 68esr, though it shows working with Firefox 48.0 and later.

Works as advertised.

just the extension I was looking for, since fanbyte blocked whole countries from accessing their sites I say good riddance!

I wish there were more starts to give you.
If I have a choice in the matter, I'll never search the web without this. It's really disappointing how some users run into a slight hiccup, maybe in need of an update, so they write a 1-star review that says "completely useless." Clearly you RageQuit and didn't actually give the add-on a chance despite it's 112x 5-star reviews.

I even figured out a way to use my free PasteBin account to create my own subscription URL. It's useful if I want to use my blacklist on a friend's computer.

It would be really cool if that were added as a feature to uBlacklist, using PasteBin API calls. Like a method() that uploads my list contents to my paste page. Just an idea.

With the new (in beta) google search 'option dots' at the right hand side of each result, this no longer works, sadly. There's no way to opt-out of the beta features (it seems to be a soft roll-out on google's end.)
It's my hope that this addon will be updated soon, as I love the features it provides. If there's any more info I can give, let me know.

SUPER.

I've used this addon for a while and it works great! Just one problem though; sometimes there's one search result that uBlacklist doesn't let me block. Other results have the 'Block this site' option, but just one of them won't have it. Not sure if it's a bug or something about the url, even adding it manually doesn't work. Other than that, great addon!

sync subscribe list plz!

This is the only extension that used to do the best job of blocking unwanted results from appearing in Google's result. WAS.
People with the talent of creating programs such as these need to realize they should never, NEVER EVER sell their valuable programs to Google!
This extension has gone down the drain....
If you see users who have placed 5 stars at current moment, those profiles are most likely fakes.

Update: 17th July 2026.
Ver 10.
Installation aborted, addon appears corrupted!

It does what it says it does.

outstanding-- perfect for blocking sites when programming like geeksforgeeks and tutorialspoint, quora, and other way too SEO-optimized sites
