Very robust and effective extension!

My only issue with it is that blocking a site overnight is harder than it needs to be, since the block time range only works if the second number is larger than the first.

That means setting 23:00-5:00 doesn't work, and you have to do both 23:00-24:00 and 00:00-5:00 instead. It works fine, but it sometimes says that the page will be unblocked at midnight even though it'll be immediately blocked right after.

Thank you for making this add-on!
