Too easy hackable :( Rated 1 out of 5 stars
This is too easily hackable!
I just made it block about:addons 24/7 by accident. So I had to find a way around this block. Here it is: you go to your firefox profile folder and rename all *.xpi files with numbers in them by adding a .bak for example. Then Firefox won't recognize these particular addons when restarted. By renaming the files back step by step, firefox will recognize leechblock again and you'll know which *.xpi it was. So just remove it. Done.
