I put this on for Reddit, Twitter and Youtube with 5 minute allowances every 4 hours. Works like a charm and has helped me really cut down on time spent

I'm productive now! though i wish you could set a 16 character random password for override, because i feel 32 is a bit too long

In firefox 66.0.2 I cannot update settings with the option " save & close " ... For some reason once has been closed up I can still joining blocked sites ... Can you actually check if this is happening ? I would appreciate if can be fixed up... Great add-on by the way. I would appreciate if you can answer me, thanks!

Perfect,

close enough.

Thanks for your VERY reactive answer <3
Meanwhile, I found a trick that is even better in my case ; I set it up on 2 minutes every 15 minutes, and does not turn off the page (so if I stay with my work group and do not change conversation, I can still work.
Omg, I REALLY DO love your add-on !! Wish I could give more stars !!

Does the job but a bit too perfectly as I set it up. I needed to stop Facebook. Well, it's done, and I'm glad with that.
But I need facebook/messages (Messenger) to keep working with some student groups ; is there a way to add some exceptions?
Thanks!
(I'd contribute if my bank account would allow me to.)

Much needed! Should be an inbuilt feature in the browsers :D. I love the "Block Set" feature, thereby I can categorize my distraction websites and set different block times for each set.

Probably a bug, but this extension slows firefox down to a crawl on Kubuntu 18.04 (up to date as of 02/25/19). Loading URL webpages takes significantly longer.

Very useful. Has all the features you would want from such an extension. Really improves productivity!
Developer is also very helpful and quick to respond to questions!

This thing is great if you have attention issues like me and love to switch to time wasting pages. Does what its supposed to do. Now if only I could make myself do that also.

This is a fantastic blocker, where I can specify precisely what I want! The only thing that I'd wish for is more than 6 block-sets, so that I can be even more specific about what I want to do with each site.

A functional and helpful addon to design time saving restrictions on the web and to eradicate bad online habits

Simple, feature-rich, and very transparent - great add-on!

I've been using leechblock for years. Great functionality, really improved my productivity. I recommend it to all my students.
