I have a similar one to yours that creates a new plain text document from text on the clipboard.
My most often used one is Open current safari tab in chrome. I prefer using safari as I seem to get the best battery life using it. I don't have flash installed so any page that may have a flash component just gets opened in chrome using that Alfred workflow.
I occasionally need to open links in Firefox (rather than Chrome) so I have a FF <url> workflow that simply opens that link in Firefox. I need to automate more of my workflows.
My alfred workflow library is incredibly sparse at the moment, so if you have any other good resources you'd like to share, that'd be great.
