I rely heavily on a modified version of Firefox's "smart keywords" for navigation, especially when opening a new tab. Unfortunately the latest version of Fast Dial on the latest Firefox seems to interfere.
With this bookmarked, typing in the letter "d" will take you to dropbox.com, while a "d" followed by a word will search Google Dictionary for that word. It's very useful, and lets you have individual bookmarks and search operators for many different sites.
Is there any way to fix this? It only started recently, when I upgraded to Firefox 12 from ~7 (I'm slow). I use these keywords at least as much as I use Fast Dial, and I'd hate to have to choose between them. :(
