This extension is very CPU heavy. I have about 90 tabs opened and in about:performance this extension regularly peaks to high cpu usage.

The thing is - I dont even want to do anything about my existing tabs. I just want a "new browsing" to be blocked.

EDIT: Thank you, I swear I went though the options but somehow I missed that one. It works now without CPU overhead. Fixed rating to 5*, awesome extension

Simple, powerfull

Je revis grâce à cette extension. La vie sans réseaux sociaux, c'est la vie : foncez.

This extension is so annoyingly good.
I use it to
- block websites I don't want to visit
- prevent myself from endlessly browsing comment sections
- have a slight delay on websites I sometimes need to visit but often browse aimlessly
- redirect myself from newspages to my (imageless) RSS-collection that's much less inviting for timewasting
And so far every idea I had just works
Huge thanks to the dev team. Amazing work there

This is one of the best browser extensions for college students ever! If you lack the will power to close your browser and stop watching YouTube or scrolling Instagram before 3am this will fix it! It is light weight and runs great. You can even add a custom URL (Like that assignment your putting off) to reroute to if you try and open a blocked page. The military time set up is a little confusing for some people but nothing you can't Google. Overall a great add on. I will not run Firefox or Chrome without it.

A phenomenal add-on with loads of customization available.

This is a really excellent add-on, thank you!

Great addon. It works perfectly, it's simple, has lots of misc. functionalities, and is free.

Does what it says it does very well. Highly recommended.

Simple and effective. This is exactly what I was looking for!

Buena extensión para evitar (o al menos moderar) el doomscrolling y los medios de desinformación catastrofistas y depresivos a los que muchas veces somos adict@s. En mi caso he bloqueado el 20m*****s.es, RT**.es, La R***n.es, El M***o.es, OKD*****.es, P*****o.es y un largo etc. de medios de manipulación y mi calidad de vida ha mejorado sustancialmente, ahora puedo despertarme, tomar mi taza de café, y leer o escuchar algo que me haga crecer y pensar en mis metas y objetivos, y no enfadarme ni creer que el mundo va a acabar al leer a estos medios.

Infinitas gracias por la extensión!

P.D: se echaría de menos un modo para sincronizar las blacklists entre dispositivos

La migliore estensione sul mercato, con le sue numerose configurazioni disponibili permette di creare comportamenti esattamente come si desidera.
