Rated 4 out of 5 stars

Yet another nice security tool :-)

Just thought I'd mention...

addons.mozilla.org accepts the faked firefox version and will filter search results accordingly. I'd expect it to gray out what it thinks are add-ons only compatible with higher versions of firefox, so users might have issues installing some add-ons.
Or, maybe not.

Either way, nice innovation in the security/privacy department :-)

This review is for a previous version of the add-on (0.0.9.1-signed.1-signed).
