rfe: allow multiple blocked objects at a time via menu

[al_9x]

something like existing sticky menu functionality for scripts

if you have multiple objects that you need to allow via the menu (but not all-of-type@site) each of which could also lead to page reloading, the ability to do multiple would be helpful

Agree, even though it's likely gonna help only the small fraction (including myself) who use "Apply these restrictions to whitelisted sites too".
Low-priority TODO, thanks.

I use that - but because I also use RP, I turn off automatic page reloads altogether .
