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.

Just works, neat and clean interface

Nice extension. It helps with doomscrolling

Great for keeping me focused and on track. I've recommended it to friends.

This is a really good and effective extension for parents and children alike. I have never seen or heard of the functionalities of the extension, but it seems to be becoming a greater necessity for those with disabilities that have severe addiction on social media.

And it has a lot of potential to be a great extension made by a passionate extension developer that just wants the necessary freedom to make this very effective web blocker addiction extension.

As a superadapted Autistic person that already suffered dozens of obstacles for the past decade, this extension has to be the best extension for parental controls, website restrictions, locking down websites, and overall the least CPU-intensive web blocker extension.

And I hope that dozens of others with Autism - like me - to start adapting and using the extension on the most efficient way imaginable.

Your extreme levels of confidence and self-determination has made me download your extension because of your honesty and passion! And I have never seen a extension this extraordinary and well-made for combating major dangerous platforms out there.

Keep up the fight against major corporations!

And thank you for creating this extension, James!

You are extremely passionate and honest, and is willing to work with Mozilla for the future to come!

Keep that momentum up!

And be always confident on yourself.

And please make open-source surfing more popular again for the forseeable future!

Also, if you have ever heard about the Electronic Frontier Foundation, can you reach them out for a collabration on new extensions for the future?

That would have been amazing if you did that!

I already started blocking major platforms contributing to the majority of the internet dangers out there, making categories for addictive and dangerous platforms and websites alike.

And I loved your work and effort on this extension. Keep it up, man!

Excellent extension! I use it when I need to study and it does a great job keeping me focused and off social media. It has plenty of customization options and different block-sets so you can curate it in a way that works perfectly for whatever you need. I highly recommend this if you have any sort of trouble spending tons of time on sites when it could be spent better :)

Wonderful extension. Has helped me tremendously with my social media use. I no longer have to spend unhealthy amounts of time on social media thanks to this extension

Look, I'll just be honest, I was a fucking idiot who hopped onto some bad shit, particularly with the AI thing, I'm stoned, I feel guilty, I let this thing take care of it for the rest of time, as it said itself
