How to prevent Firefox from copying numbers or #'s when copy and pasting on a Mac?

When I copy and paste from a website that formats their text using <*li>, I get numbers or #'s when I paste into any text editor on my Mac (running Snow Leopard). Is there anything I can get that is equivalent to Windows Notepad, that will NOT copy the formatting, and just give me the text? Example of a site that I copy/paste from that gives me #'s or numbers:

Use Paste As Plain Text in Word or Open Office or use a pure text editor like SciTE.

Most Cocoa applications that have a text editing interface have a Paste and Match Style option in the Edit menu. This will paste the text without pasting formatting.
