Ever seen a URL in an email from someone using some braindead product that wrapped the URL onto the next line, making it unclickable? You've probably either grumbled about it, reformatting it yourself with a text editor or something, or in most cases, simply not bothered visiting the link. Thankfully, if you use Firefox (and quite frankly, if not why not) the solution is here.
Type in about:config into your location bar (full of all sorts of other cool config options too) and find a preference named "editor.singleLine.pasteNewlines", and change it from the default zero to something like 3. Highly useful. [Via] [Via]
