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.

I have been using this for years, and I was delighted when the author took the time to rewrite the extension to work with newer Firefox versions, and with Chromium browsers too! Well done! It also works with Firefox Sync (go its settings to enable that). The settings are a bit hard to understand at first, but there many more settings than anything else that I've tried.

The only thing that it lacks is that the settings page is not suitable for small screens on Firefox for Android.

This is the first browser extension that I have ever donated to.

Made an account just so I could rate this.

The delay page really is the killer feature for me. I can set the timer to just long enough so that I stop the impulsion, but just short enough so that if I really need to access something during the block period I can, if I feel like waiting (which I usually don't). Alt-tabbing also cancels the countdown by default. The statistics breakdown for each blocking group is also brilliant.

There's a lot more features to this extension I haven't tried, but for now the way I have it set up works really well.

All of this under a copyleft license means a big thumbs up from me. I can't give enough praise!

I'm not happy to write this review.

I always thought that Leechblock NG was perfect, but yesterday I found out that I can easily disable it by going through the add-on options. Without typing the random password.

I have tried to follow the instructions on this site https://www.proginosko.com/leechblock/faq/
But after hours I didn't solve anything.

I think I'll try "FocusMe" software.

Finally a blocking extension that has everything! Clever grouping of sites with functionality for: delaying access, setting a max time and setting a schedule. And even if one site is in several groups and has multiple rules tied to it, the blocking rules interact and work together as one would expect! Very happy with this.

When you can't control yourself with social media, to use this app would be helpful, if it wasn't so easy to disable in Firefox's options. You can even unblock the site at will. There is nothing an extension can do with these things, so try out an app. I'm trying FocusMe out, if I find it for free somewhere. It's not a bad extension, it's just too easy to get around it if you have no power over yourself. I hope this gets checked out and helps someone.

this is my first review and I consider this extension one of the best ;

So so so useful if you have trouble staying off distracting web pages. Works flawlessly and is fairly straightforward to configure and use.
