OpenStreetMap
Just created new search plug-in for FireFox to search within wiki.openstreetmap.org , can be installed from here:

While using JOSM sometimes there is a need to find detailed description of the tag or tag set, this plug-in should simplify this search a little bit.

wiki.openstreetmap.org already offers a search plugin on-site. It can be added to Firefox by clicking on the search box icon (while wiki.openstreetmap.org is open in the current tab), then scrolling down in the drop down menu and clicking on the plug-in's entry.
Does your plug-in offer any additional features?

Probably it is not giving anything new. MyCroft have tons of Firefox search plugins and I hasn't found this search plugin there. Just a guess, what you desribed is a mediawiki feature?

Yes, the feature seems to be present at most MediaWiki installations, so I think that MediaWiki (or some extension) creates a search plugin and sets the proper header by default.
