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": ["[email protected]"]
},
"ExtensionSettings": {
"[email protected]": {
"installation_mode": "force_installed",
"install_url": "https://addons.vaultpit.io/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.
