Useful addon

Is there a way to use larger lists?
The current version has a limit of about ~180 url's.
If I insert a larger list, it is not saved.

It also would be nice to be able to know when an addon is blocking a site (for example, changing the color of the addon icon or site favicon)

There is a small bug:
If I add a site to block, check it, then remove it from the list (i.e. the list is completely empty), the site is still blocked until I add a random entry to the list.

Very interesting

simple and efficient

Works as described even on Firefox on Android. Simple but very useful in blocking sites that ruin your productivity
