I often type long URLs into Firefox's location/address bar (usually a URL with many GET parameters).
Since I must scroll left and right in the location bar to see the entire URL, it's hard to edit.
What plugin lets me edit the address/location in an external editor?
Or at least edit the GET parameters I'm sending and then re-send the request?
I realize I could use "firefox -remote" from the command-line, but that seems ugly.
