Bit.ly Firefox tool
See full URL and number of clicks on Bit.ly links
Use this link https://addons.mozilla.org/en-US/firefox/addon/10297 to download and install the Bit.ly Firefox addon.
This tool is great for using on Twitter. On rollover it displays full URLs for Bit.ly and Tiny links. Plus shows user details when you rollover twitter handles such as @gossinteractive.
Bit.ly tip - only use short URLs on Twitter. Permalinks are much better on other sites (Facebook, LinkedIn etc) as this will improve your SEO.
