This extension has been a game changer for productivity. While it took some experimentation to set up, the program works every time. I can't recommend it enough.

It help me with my addiction of YouTube, I do not use Instagram or Facebook, but this plugin help me to combat my addiction. Highly recommended, especially useful during work hours.
Thank you, James Anderson!

Very helpful tool to prevent doom-scrolling and wasted time.

Very complete add-on. Actually blocks subdomains properly so i can stop myself from getting absorbed into watching shorts with youtube's intrusive recommendations but still usw the site. Great blocking options, customizable, and gotta appreciate that it's free.

Extremely simple to use, but very effective, really improved my discipline

amazing add-on for helping me focus; I use the delay-page option so I'm forced to evaluate whether i want to waste time on youtube for 60 seconds before it opens.
I recommend taking the time to understand the functions because it can block pages in a lot of ways depending on what works for you.

Once again, this addon is a life saver, especially for someone like me who gets easily distracted while online. Love the wildcard option. For example: I have blocked google news on week days. However, if I search anything on google search and then click on the news option, I am able to see news stories related to my search. Using this "*google.com/search?sca_esv=" as a wildcard blocks it perfectly. Maybe a bit extreme, but much needed to get away from the internet. Thanks again.

Generally a very good idea to boost productivity with minimalist UI in place, but it's also easy to bypass as extensions can be disabled/removed in Firefox reverting their settings.
