Probably one of the best, if not the best addon made in the era of digital addiction. What really makes this the best is the level of customization it allows. One feature I've been using for some time is the grayscale one. Making everything grayscale just makes watching videos for hours much less engaging, which is good.

One thing I was not able to do however (and that's not really a flaw, but more of a very specific combination of rules) was to be able to make all pages grayscale except ones that have .png, .jpg, .jpeg, etc on their url. I've tried * +*.jpg +*.png +*.jpeg but I was not able to make it work this way, even though it works with more clearly defined urls.

Anyhow, many thanks for making this.

Excellent, simple to use, highly flexible so that you can setup the kind of help you need. It really helped me improve my focus at work.

Works almost as intended. I blocked Youtube for starters and as long as I'm actively interacting with or giving focus to firefox, the counter is ticking down. The moment I'll click on something on my second monitor (in this case, Discord) the counter stops after two seconds. This has been reproduceable. I'll use it further as a reminder for myself, but sadly it's not working as I need it right now :/

Edit: Thanks! Is working as wished :)

I can't thank you enough. I have installed old version of firefox just to use leechbock.

This ad-on saves my life! it is highly customizable, and can surely support your needs. I love you LeechBlock devs :)))))

Just when you thought there was no paradox in leech blocking to be found, Prof. James Anderson displays a thorough "analysis of its character, presence, and epistemic status" for the interwebs! Well done...

It works almost perfectly. I hate it. Uuuuuugh, guess I'll go back to work. Anyway, it's 4 instead of 5, because the temporary unblocking feature doesn't seem to work. The icon is yellow and everything, but the websites aren't unblocked.
Edit: see developer response, it was user error.
