Altered userContent.css for Firefox to style StackOverflow blockquotes to look different than code blocks.

userContent.css

/*
 * Sets blockquotes on stackoverflow.com to have a yellowish background
 * with a box shadow, instead of the same background as code blocks.
 * Helps to show code inside of blockquotes.
 * 
 * Sets links to be underlined by default so multi-word links and
 * single-word links can be distinguished.
 * 
 * Should be added to ./chrome/userContent.css in your Firefox profile
 * directory. Profile directory can be found by clicking "Help", then
 * "Troubleshooting Information". Then, look for "Profile Directory"
 * and click "Open Directory". (Wording may change.)
