[Edited] Nice plugin which works as expected AND has good support. Note: For the override feature to work, be sure to enable "[X] Allow temporary overrides" in options. This has stumped me, but the dev looked into it and figured out my problem, which means extra points for support. :-)

Great addon, but not recommended for laptop users, as it seems to eat CPU. Loading up the about:performance tab shows LeechBlock consistently consuming huge amounts of CPU whilst doing nothing. Had to reluctantly uninstall it.

Excellent !!!!

Great - very useful to keep addictive websites at bay

Easy to set up and use. Life-saving aid to break addiction to social media websites.

it has everything i need. Block page and let me study. very good work

Best app

The best add-on if you want to stop getting distracted when you need to get work done. Very simple interface and super easy to use, have had no problems so far!

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