I tend to bounce between OS X, Linux, and Windows on a daily basis.
It would be great if the shellexec plugin for Firefox could adjust to the current operating system and adjust its commands as needed (ex regedit would not be available, but ping and ssh would be, etc) and how they are executed (via bash or command prompt).
Similar features have been implemented by the FoxRunner plugin for Firefox.
Would love to see this feature!
Thanks!
