That's exactly what I've been looking for! Many options that allow sophisticated site blocking, based also on time of the day (unlike others).

An addon that provides you with all the options you need to block what you dont want to able to access.

Very useful to help against procrastination and addictive websites. Flexible in a way where you schedule when you want to block certain pages. Also allows blocking access to settings, which helps stop impulsively disabling stuff to override the tool.

Does everything I want from a distraction blocker. Fully recommended.

Really helpful for restraining amount of day I throw away on browsing the web.

I despise this extension which means it's doing its job perfectly.

Extremely customizable, requires a process to override making sure it's blatantly obvious you're committing to breaking your own restrictions, can have multiple separate blocksets with different amounts of time allowed and allows multiple scheduling options, too.

işini iyi yapıyor 👏

I have been looking for this for so long, Thank you for making this add-on.

does what it says on the tin

This amazing!

the add-on has saved me from being homeless

Best add-on!

The best productive addon i had ever seen in my life!!

Love the flexibility of this extension. Allows you to set up multiple block sets with their own rules, time limits, and schedules. Has settings to block or discourage you from accessing it's own settings, which has been great for stopping myself from just switching the blocks off like with other extensions. Requires some initial setup, but has changed my browsing habits for the better. Thank you!

Muy buena para bloquear mi adiccion a twitter.

Excellent for weaning myself off instant gratification sites like social media - I set myself 3 minutes per hour (enough to find out anything I need) and then get a 1 minute wait if I want to read more (enough to discourage me)

This was everything I was looking for in a blocking extension. Tons of options, different block sets, allowing for limited use times, days of the week, everything, and it's free.
