this is very nice, but it has a way to go before it is great.

Problems

1. go to http://www.dictionary.com/e/s/ough/#ough

when you migrate to the next "screen" (with a left or right arrow the way that site is designed), DH adds a second [DH] header to the URL. And then a third, fourth, etc.

2. The boxes for the entry of website names need to made much wide. (Yes, the text "overflows" to the next line, but that is messy looking at best).

3. The stuff about "always clear" domain filter is sketchy. First, "always clear" is not to be found. Secondly, it does not appear to delete entries from the past when I activate a new filter. To have it clean up the history at the start would be great.

This is great but every time I start firefox it opens the addon settings page for this addon! It's annoying.

Also I can't make it work to match moz-extension:// pages, both "[a-zA-Z0-9]{8}-([a-zA-Z0-9]{4}-){3}[a-zA-Z0-9]{12}\/" and "moz-extension:\/\/" don't work to delete addon pages from my history.
