If you are a web developer, like me you have probably grown to rely on FireFox as a web development tool. Whether you develop with Drupal, Joomla, CSS / HTML, PHP or some other CMS platform or language, it's surely a staple of your web dev toolbox. Lately, it seems that FireFox 3.6.x for Mac has been running very slow and has become quite bloated. I often get the infamous spinning wheel after the browser has been running for more than a day.
