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!

So great. Can't live without it now.
