Firefox extension to fix Google’s “define:” feature

For the last few days the “define:x” feature of Google hasn’t been working for some people and apparently Google are unable to reproduce the problem. Luckily I came across a response on this Google help forum post today saying that changing the URL parameter “q” to “query” fixes the problem. I use the define feature a lot so I spent an hour throwing together a Firefox extension as a temporary fix to save my sanity while I finish off my dissertation! The extension detects Google queries beginning with define: and renames the q parameter automatically.

Install it here, it should work with all Firefox versions from 3.0.* to 4.0.*.
