NoScript Anywhere is the excellent NoScript Firefox addon retooled to make it easy for porting to Firefox for Android, Maemo and other platforms:
NoScript 3.x is implemented as a restartless add-on for Firefox Mobile, meant to explore the issues and the challenges posed by the Electrolysis multiprocessing architecture to a NoScript porting.
It also features a new page permission editing UI, specifically redesigned for smartphone usage and easily accessible by tapping on a navigation bar icon.
Once installed (with no need to restart the browser), it blocks every script and embedded object (plugin content and iframes) unless the loading resource is whitelisted.
NSA’s whitelist is implemented as a JSON map, having domains or URL prepath components as its keys and custom permission sets (or reference to the TRUSTED and UNTRUSTED predefined permission sets) as its values (references are serialized as 0 for UNTRUSTED and 1 for TRUSTED).
There developer also has plans to use Firefox Sync to sync NoScript settings across platforms. That would be awesome.
