We've created a simple Firefox search plugin.
This plugins lets you search on the entire Open Source Vulnerability Database (http://osvdb.org/) inside all text.
You can get it from Firefox addons site
https://addons.mozilla.org/en-US/firefox/addon/45607/
At this moment the addon is in "experimental" mode. It has already been nominated to public, and hopefully in a few days Mozilla moderators will approve it.
Hope you enjoy it!
