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 :)

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 :)))))

Works as intended, but ended up disabling it when I discovered it is the reason that Firefox is never idling. So I have many tabs, and this plugin is always keeping 10% of the CPU busy (2 processes at 5% each). Disabling the plugin makes the problem go away. My version is 1.0.7.

The workaround mentioned in the FAQ did not work: count only active tabs setting did not make a difference for me.

The reason mentioned in the FAQ for this behaviour is:

> LeechBlock reviews all open tabs every second, to keep track of how much time is spent on the sites listed in your block sets and to determine whether any sites should now be blocked.

I do not need this "feature", I just want to disable access to certain websites from 9 to 5. Since I can't disable the feature, I had to disable the addon and search for a simple one.
