I have tried several website blockers (specifically to limit my YouTube habits), and I've never found one like this. For free, you can very easily set time intervals, protect with a password, etc.
Great extension!

excellent at the annoying TEMU PAGE...which is dumbing down the world...quickly and in all versions "killed" !!!!

ausgezeichnet bei der lästigen TEMU SEITE...die die Welt verblödet...schnell und in allen Versionen "gekillt" !!!

For years, sites with paywalls have been driving me crazy.

Your app has given me a solution.

Thank you.

One of the best extension that make firefox different from all browser, such extension was not found on any browser

Это прекрасное расширение, которое помогает мне эффективно управлять доступом к веб-сайтам. Я ценю его гибкость, защиту паролем и возможность кастомизации сообщений на заблокированных страницах. Отличный инструмент для создания безопасного и удобного веб-пространства на рабочих ПК.

I spent hours trying to find a comprehensive solution to block unwanted websites esp. subreddits and finally i found this ! It has all the features that i need and more.

For those who have complained, i suspect it's cos you do not know how to use wildcards/regex to add custom websites and keywords. Best bit is this solution is FREE unlike many others out there !

This could potentially be a lifesaver for me.

The only concern that i have is what kind of data it is collecting, especially if it's collecting any private and sensitive data.

Excellent! Works like it should.

wonderful

I've used the add-on pretty sparingly, so when I tried to add a site today I was frustrated that the block didn't seem to take. It was user error, however. Once I disabled, then re-enabled the add-on, it worked like a charm. Hope I remember this next time...

My procrastination is so bad that I just disable this addon in my browser settings. I'm dying.

its working
