amazing productivity extension that can block sites and also can let you set a specific timer before it lets you access a site

This extension is a lifesaver in the modern landscape of every single website ever trying their hardest to keep your attention for as long as possible

Awesome!

Does what I need it to, nothing more to say.

Absolutely wonderful Firefox extension. Many settings to tailor to your needs. Works as intended!

Very very good, helped with my procrastination

もともと、Blocksiteを使っていたが、無料でできることが少なくて、代替サービスを探していたところ、この拡張機能に出会った。無料ですべての機能が使えて、最高の拡張機能。仕事中、勉強中に関係ないサイトを見てしまう人はぜひ導入してみてください。

What a stellar extension. Practically every possible arrangement of options is on the table; the settings take a little bit of fiddling and figuring out, but the documentation is quite good, and although I haven't needed to use it I believe the support forum is also.

The only thing I haven't seen (which would just tickle my particular ADHD brain in the right way) is having the "time limit after which to block: x minutes in every Y hours" be a hard block, and a delayed block (for 60 seconds, say) before accessing it even for those X minutes!

Overall, I'm very grateful this exists. Thank you for working on it! I think it really helps a lot of people.

Looks as though some of the one-star reviews here relate to the author's view of the world. For what it's worth, I think I'd agree with people posting such reviews that the views they attribute to this extension's author should be addressed publicly, and that we should shout the more-caring and more-loving attitude louder than anyone else can shout their less-caring and less-loving views.

Still...reviews on a firefox extension are an odd forum to try to have that conversation, and more importantly than that, I think we can all agree that views like that don't change by one-off internet conversations. Views like that only change when the people who have those views are forced by circumstances to have close respectful relationships with people who suffer because of those views.

Excellent extension for ADHD monkeys like me. Fine-tuning tips. Exceptions are supported.

LeechBlock NG is a masterpiece on the desktop, but be careful if you are using it on Android to fight a serious scrolling addiction.
​The "Advanced Options" that allow you to block about:addons or about:config simply do not work on the Firefox Mobile app. On Android, the Add-on manager is part of the browser's native UI, not a web page that the extension can "hook" into. This means there is no way to prevent yourself from simply clicking the three dots and deactivating or deleting the extension whenever you feel a craving for YouTube or Instagram.
​If you are like me and looking for a "hard lock" that you can't bypass by just deleting the addon, this isn't it for mobile. On a PC, you can use the password/USB-stick trick to lock yourself out of the settings, but on a Samsung or any other Android phone, the browser's own menu provides a permanent backdoor.
​Pros: Same great filtering engine as desktop.
Cons: Cannot prevent deactivation/uninstallation on mobile due to Android Firefox limitations.

Extremely helpful in order to prevent myself from doomscrolling randomly throughout the day. I feel like regaining active control of my consumption, given how interconnected social media and in general, highly addictive services are within the internet are. Although the interface is not particularly beautfiful, I recommend this to anyone willing to regain some control.
