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

While I am so far indeterminate of the effectiveness of the extension, I feel I am personally obligated to give this a one-star review as the developer holds several viewpoints that I find not only personally offensive and disgusting, but also contributive to harassment, abuse and violence that impacts millions of people daily. The viewpoints in question are transphobia, far-right Christianity, and (heavily implied) homophobia. While the developer may have changed his opinion on these topics in the several months that he has not posted them on his blog, in which case I would be thrilled, I find it likely that he has not; hence this review.

Furthermore, I would like to note that he speaks eloquently and passionately on these issues, which I respect. I am usually not one to judge based on political views and am of the opinion that it is only through communication and interpersonal understanding that we will achieve peace and cooperation. This is not a personal attack, per se, and there are still qualities about him that I can see and appreciate; he must simply change his opinions and all shall be well.

If he is open to discussion regarding these views, he may contact me at gwimauve@gmail.com. I ask of nothing but a simple sharing of viewpoints; I wish to understand this mindset better.

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

Extremely useful to help me get out of YouTube but also other sites toxic for your attention.
Très utile pour m’aider à me desintoxiquer de YouTube ou de tout autre site toxique pour votre attention.

Dose exactly what it says it dose and dose it great. Very customizable.

may the god bless you james.

LeechBlock is a game changer. I really like the different options & it has really helped my focus at work.

Really helpful.
