I have a new favorite Firefox add-on. Its called “Copy as Plain Text” and it does one thing. It allows me to copy text in Firefox to my mac’s clipboard with out the formatting. So if Something looks like this on a web site > YUCK I can copy it and past it anywhere and it will look like this > YUCK. Simple!
If you really hate formatted text you can also set this plug in to remove formatting by default.
