Since I was in the mood of creating FireFox search plugins for sites I search on often, I decided to make a search plugin for engadget. So, here it is:
Install Engadget Search Plugin
Just click the link above, and it will appear in the search bar within FireFox.
Again, sorry for the crumby icon (I obviously have no design sense). If anyone can make a better one, let me know and I will update it.
