Multiple search bars in Firefox?

[Trinithis]

Does anyone know any extensions for Firefox that allow me to add as many search bars to my firefox gui? Preferably for each one added, there would be an option in a right click context menu to use that search engine (as a new tab) when text is selected.

I tried installing http://www.oxymoronical.com/web/firefox/Thinger, but it isn't compatable with my version of firefox (v3.0.13).

While you can always edit the install.rdf you won't be able to add new search boxes. This could be useful in the meantime
