Windows/Mac/Linux (Firefox): Save yourself the time of copying, pasting, and fixing mistyped links with QuietURL, a free Firefox extension that converts URLs with typos or bad formatting. QuietURL comes with a standard set of common fixes, but users of regular expressions can get ultra-specific on what gets fixed. If you're a regular browser of a forum or site that willfully obscures URLs by messing with the link code (as in "hxxp:// ..."), QuietURL can automatically fix those as well, or pull the reverse. For those looking to fix their own fat-fingered URLs, try URL Fixer or switching your router to OpenDNS. QuietURL is a free download, works wherever Firefox does.
