Simply excellent and flexible. Only request of the developers it make a simple checkbox in this general options tab to essentially put 'about:addons' and 'about:support' and 'about:config' behind a password at all times. The workaround to protect Leechblock from being disabled (including by Firefox 'Refresh' or 'Restarting with Add-ons Disabled'/Safe Mode) requires this. I'm sure this will be addressed soon because the development team has proven very responsive by email.

Very usefull since it allows a daily buffer of time.

Very useful, light blocking plugin. Much easier to use than my previous plugin.

Absolutely excellent. Helps me staying productive.

It's a great application that is flexible with how you block sites. I personally like its ability to delay gratification. I have it set to delay opening websites by 45 seconds. Thank you!

5 stars if I could figure out a way to block an index site (home page) and have sub-domains not be blocked by default (manual exclusions aren't suitable if you'll want to access pages via a Google search, for example). Other than that works great.

You did a great service to humanity James! you've saved thousands of hours of mankind! I wish I could donate you but US governments restricted our access to Paypal in Iran.

Works really well, it saves me a lot of time I would otherwise waste with scrolling through YouTube or Reddit!

I have noticed that it is very easy to access the blocked sites by disabling the Addon from the addons page, which takes only a few clicks. This is probably not changeable from the extension code (to prevent bloatware extensions from blocking their removal), however, you can lock the extension yourself using the Firefox policy system, which prevents removal https://support.mozilla.org/en-US/kb/customizing-firefox-using-policiesjson

For reference, this is what I put into my policies.json:

{
"policies": {
"Extensions": {
"Locked": ["leechblockng@proginosko.com"]
},
"ExtensionSettings": {
"leechblockng@proginosko.com": {
"installation_mode": "force_installed",
"install_url": "https://addons.mozilla.org/firefox/downloads/latest/leechblock-ng/latest.xpi"
}
}
}
}

This way, you have to remove the file and restart firefox, for me this is cumbersome enough to stop me from disabling the extension.

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 :)
