I don't even use the straight-up blocking function that much, even just the delay function works like a charm to keep a mindful eye on surfing and social media habits. Simple yet customizable and effective, this has got to be one of the add-ons I most often recommend to others

Very helpful as someone with ADHD! I like being able to allow different amounts of time for different sites/groups of sites.

Free and with all the feature of paid product. Lovely!

Could it be possible to specify a local HTML as block page? Thank you!

Works just perfectly fine, especially when you are trying to build habits for yourself.

It's not a silver bullet against procrastination, but it is, like, a regular bullet, and those are pretty useful too

My man James is a lifesaver actually and deserves so much credit, still figuring it all out but BOY has this saved my skin many a work day over these past few years

Time block is not optional.

Screen says 'Enter the time periods within which to block these sites (optional)'.
But leaving it empty makes the plugin to skip everything in the list. So not optional at all.

Excellent plugin for browser, but has become completely unusuable on mobile. Requires opening the extension and saving options again to get it to start blocking the current tab, which defeats the purpose.

edit: seems this is on Firefox's end, solution is possible by not using filters (I think)

We wrote about how this extension makes firefox unresponsive, though it kind of is our fault for having 20 000 tabs open.

The developer responded -immediately- with a fix which we really appreciate and were surprised by. They told us to go to enable a performance setting in the general tab, that only considers active tabs.

However, the fix didn't work. It made firefox a little more responsive, but in that we only had to wait one minute per interaction with the browser instead of three.

worrks well
