No doubt one of the most useful and important extensions. 10/10

The reason I get any work done in these days when there are so much distractions.

This app saves me from wasting hours on social media EVERY SINGLE DAY! :)

This addon has saved me from youtube. I used to sit at my computer for hours watching youtube but now i can use my computer again without getting distracted.

Although the settings examples at the developer's website are very helpful, it would be nice if the website's FAQ was expanded to explain each line of the settings, because I didn't find the settings easy to figure out. But this is partly because Leechblock is such a powerful, flexible program. Customer support is great too. I'm very glad indeed that I found this program; it's just what I needed.

Leechblock behaves unexpectedly.
I created a block specifically for YouTube but then I wanted to modify the times. The modification remains in the options but the add-on's behaviour was NOT changed. So I decided to delete the YT block and start over. BUT EVEN DELETION DIDN'T ERASE IT! YouTube is still blocked even though it has been erased! The result is I have to disable the add-on completely to watch YouTube. Frustrating.

Does everything exactly as advertised. Wish it was available on Microsoft Edge as well.

This is great and I really do appreciate the number of options. However, I would ask that you guys add the timer into the dropdown when you click on the addon tile in firefox so that it is easier to see at will. Also, please integrate the timer feature for lockdown as well. I use this feature more because I like to be fluid when I study, there is no apparent timer to show much time I have left. Its actually pretty annoying.
