Are you sick and tired of websites, especially technical ones that have complicated commands or code snippets, preventing you from copy/paste? Here's a fix that website owners HATE!
Open Firefox (because you shouldn't be using anything else), and in the Awesomebar, type in "about:config" and press enter. Accept the warning. Search for the option "dom.event.clipboardevents.enabled" and set that sucker to FALSE.
Take back the web!
