Reverberations

I need one Firefox extension/greasemonkey script to add an option to open xls/doc links directly in Google docs & spreadsheets. This is something Google itself should be providing like they do in Gmail. Perhaps, I’ll write one myself in case I can’t find it.

[Update]- Whooaa! Same day Google releases its Firefox toolbar (beta) with this exact same functionality I’m looking for and have blogged. Now, is it just one wish a day, or - I want to be king , please.
