This add on is all I need, thank you so much, no complicated bullshit or needless timers, just a blacklist and toggle button.

no more distractions

The only addon in this category with the "redirect to url" feature I was looking for

Wow, thank you- this extension is great! Hopefully I can get my productivity back, from the likes of YouTube, reddit, and Mastodon, now. :p

verry good!

works just fine, blocks any url you want. its also completely free, great alternative to some other paid website blockers.
one thing id love to see is a schedule option, for example "turns off at 7pm, turns back on at 9am"

I would love to see an option to automatically enable that block during certain times of the day. e.g. from 8 in the evening to 8 in the morning, so Facebook and YouTube won't mess with my sleep.

simple and working

Excellent. Absolutely wonderful for ADHD! Even better when combined with Rainy Mood! (The power combo!)

no cut and paste. even after blacklisting a site some things still persist.

works flawless! I have to write this review to distract me from work...

Awesome addon. please increase time limit.

It does exactly what it does: blocks me from going into distracting, time-wasting websites. I needed that for my Firefox and this is very helpful. Highly recommended.

Easy to use add-on which really helps to stay focused while working. It has two modes: one disabling access to blacklisted websites and other enabling access to only whitelisted ones. I really like the minimal approach enabling you to use it without any additional stuff like visual customization and other unnecessary options. Does what should do really well!

Does what you think it does: overlays the website with a blocker, has an on-off-switch, blacklist and whitelist mode. It easy to add URLs
