It just doesn't work. It can block the main page of a site, but refuses to block any page related to it. I want to block a social media site to stop myself doomscrolling. It will block the frontpage and no other page. Even if I put in the address for the other pages I want to block, it won't block them. WHY!?

Suddenly stopped working. Can't add sites to blocklist, pages on the blocklist aren't blocked consistently.

Doesn't work anymore for me on Windows 11. It used to on Windows 10. Waste of time.

Yeah, Random Sites Started Popping Up and it Wanted to "Disable WebExtensions"??? I Don't Care if this Add-on comes with a decent 3.9-Star Rating [That's a 78/100, a C+ Grade] (Out Of 512 Reviews) & 73,320 Users (as of 10/10/25) - if it opens stuff randomly over & over and asks that of me, I am concerned about my PC, You Never Can Be Too Careful These Days with Scams, Fraud, & Phising, afterall. An Excellent Idea, However, I'm Concerned About This Add-on's Authenticity & Security, & Will Not Be Running it On MY PC, for sure.

I need a solution to temporarily block access to a few opened tabs. But this add-on doesn't block tabs temporarily, it destroys them permanently.

Worked for exactly one day, the next day it stopped working entirely. Tried reinstalling it, using regex, changing configurations, and nothing.

Didn't work... Elaborating, it didn't work after adding a regex rule (maybe I should have tried harder, but I kind of quit after half a dozen tries, as the extension seems to add characters to the beginning and the ending of all inserted rules, regardless of them being necessary or not.) Even if it had worked, it'd be amazingly cumbersome to manage the rules, as, after added, they cannot be edited, just removed (there's an option to load a local text file with the rules, one per line, but then again, to edit one single rule, it requires the clicking on a purge button that removes all rules, then loading the file again...) It could simply have the rules in a textarea for free editing, like other blockers do, which would make it much easier to manage.

The new update stopped allowing this extension to run in private mode. please fix, otherwise than this I give it 5 stars.

Used to be amazing but recently stopped working

used to work some (long) time ago, now it doesn't

DON`T USE THIS PLUGIN EVER! I had to report it.
When you have websites blocked, this plugin ruins all those tabs you have opened. it does not only forbid access temporarly, it corrupts the entire tab so it will never be accesivble again!

Also, the Ad-On is very unintuitive. but the main problem is that it will destroy your tabs.

Mozilla Firefox should not allow such a plugin.

Almost impossible to use and block sites

i thought this add on would just block me from accessing a website but instead it ruined all of my previously open tabs in a catasthropic way by changing the url. it just nukes your archived tabs, DON'T USE.

I lost my time trying everything to make it work, but impossible to start the blocking.

It doesn't work. I added the site I wanted to block, saved the settings, but it still opens the website. Useless add-on.

nem blokkol semmit kalap szar

Does not work, I input a site save the changes and the site is still available. useless bloatware

I cant mark the time period of the site will be avalible.

Not working

I installed the plugin and I don't even see a block button. I'm using Firefox v. 130.0 (64-bit)
