How can I assess the trust worthiness of a browser add-on?
==========================
Having learned a bit more about what add-ons/extensions can do in Firefox, I want to minimize my risk and use some safer mechanism to download videos (FLV in particular) for later viewing.
Considering the question http://security.stackexchange.com/q/5875/665, is there any way to trust an (open source?) browser add-on? I can examine the code myself if it's not 100,000 lines of illegible gunk.
The most popular video-downloader add-ons are closed source AFAIK.
