Mozilla Firefox

Although Runstoppable works in Internet Explorer (6+), we strongly recommend that users switch to Mozilla Firefox since it has better support for some of the site's more advanced features.

Firefox is a free, modern, easy-to-use, secure browser that is available for all common systems (Windows, Mac, Linux, etc). Firefox does not replace Internet Explorer, you can use them both side-by-side if you wish, and if you don't like Firefox, you can remove it cleanly.

We're pretty confident you won't regret trying it out. If you have any questions, feel free to email matt at runstoppable.com for more information.
