I am a huge fan of this app and would recommend it to anyone

This extension really helps me keep me accountable to myself, and to not let my lizard brain dictate too much of my habits.

Best addon to combat social media addiction. Even when you can override it with a few clicks it really helps to reduce it.

Great experience. Multiple block sets help in choosing different combinations.

Simply excellent and flexible. Only request of the developers it make a simple checkbox in this general options tab to essentially put 'about:addons' and 'about:support' and 'about:config' behind a password at all times. The workaround to protect Leechblock from being disabled (including by Firefox 'Refresh' or 'Restarting with Add-ons Disabled'/Safe Mode) requires this. I'm sure this will be addressed soon because the development team has proven very responsive by email.
