Firefox: copy HTML source?

I didn’t find a solution for this, so I’ll just bump Omegatron: currently, to copy the source code of a web page to clipboard, you need to

  1. highlight what you want to copy
  2. right click
  3. select ‘View selection source’
  4. push ctrl-c (or right click and select copy).

Am I going to have to start hacking together a Firefox plugin to make this simpler?
