I've tried many things, but only this, simple as it is, has really worked for limiting the time I spend online.

Fantastic addon, please give an option to block all websites with one click.

works like a charm, saves a lot of time, literally.

Great for people with who spend too much time mindlessly browsing sites like YouTube. Only problem is that there is no auto-pause for video players.

I've been using the add-on for 454 days (at least, that's my longest current streak :)) – the extension does its simple task of preventing me from distraction and does it very well.

Doesn't pause and let me know if my set time is up if there's a video that's set on full-screen, so it sortof throws the whole point of the add-on out the window.
Other than that, works great.

I think i've tried every extension along these lines there is, this is easily the best one. My only complaint is the ridiculously large UI - I shouldn't have to scroll to see all 5 of the UI buttons on my laptop...

The app is fluid and works with no bugs. I love that you can have focus time and limits on certain sights. Great tool to fight digital addiction.

It's perfect for stopping distractions! I also didn't realise how much the streak feature made a difference until I almost lost it - keeping the streak going is good motivation! Excellent and well made extension!

Amazing extension. The only complaint being the odd zoomed-in popup display when I click the button: https://imgur.com/a/jgVRatD
