I love this extension. It has greatly improved my life.

Also, I would like to make a feature request. Please add a youtube video blocker inside leechblock. the current popular video blocker extension doesn't work for the new Youtube and leechblock could easily fulfill the need for it.
Thank You!

Simple, and functional

Great tool! Thank's for providing it for free!

Very versatile, so helpful. Good job, keep working!

Switched to this from the ImpulseBlocker addon. I can set times when I want to be productive and disable social media websites during that times, also set times for sleep and for weekends, that's pretty easy to configure. Overriding the self-set rules is hard and that is important. ImpulseBlocker had this "disable for 5 minutes" button and I used that way too much. Synchronization over your firefox sync account seems to work for me as well, though it is still in beta. This helps me a lot during this Covid19-induced home-office.

Allows much more customizability than other timer apps I've found. That means I can keep my schedule in the Goldilocks zone of productivity and enjoyment. Thus I don't need to keep using willpower to reset it every time I want to avoid certain sites, and don't risk "forgetting" to use it.

However, the UI could be more intuitive - I often accidentally set it to do things I don't want. The override also doesn't work for me even though it displays a messages saying it has. This is a problem when I need to use certain sites. It happens whether I activate override before or after I run out of time.

This tool has been the biggest help. Clearly, the author of this tool understands the doctrine of total depravity. :-)

Edit: lol nvm i didnt realize there was a website with a FAQ, it's crazy how powerful this is
---original: these things exist!---
I wish there was a whitelist feature, because sometimes wikipedia and a bunch of other sites i can't list all of are useful for work and other times they're a distraction.
Also, it can't kick me off of a site that im on, it only blocks it when it refreshes. Tumblr is an endless scroll site and if i run out of time it doesn't kick me off until i manually refresh it

Me writing this review is a sign that it is working. I would definitely be on social media if it weren't for this add-on. I used the Stayfocusd extention for Chrome previously and this add-on is a perfect replacement.

Simple to use, has a number of powerful options, and a pleasant but unobtrusive default "sorry, can't visit" screen. Works great!
