It blocks scripts alright, no problem there, great job, it does exactly what it says it'll do, so a great rating suits. However, I haven't given it 5 stars because I'd like to see 2 features added, of which at least the first shouldn't be too hard to implement IMHO and the second probably not either, although I haven't looked at the code, nor have I ever scripted a FF plugin myself so I should stfu, I know.

Requested features:

1. export/save+import settings, so I can just import all my preferences instead of having to point it out to the plugin for each and every site again when I have a new machine/new OS install

2. settings per domain. Eg I wanna disable google's js-es everywhere, except then the drive.google.com becomes unresponsive, warning me that js needs to be allowed. So, I'd wish to allow google's js *only* when the address bar shows a google.com url and disable it on every other site.
Here, I'd like to list on which sites in this case google's js may be enabled, bc eg youtube.com (which for now actually doesn't seem to need google's js) is also from google, so I might wanna choose to allow it there as well (theoretically speaking)
