Why can I launch tests in FireFox 3.6?
Currently, it isn’t possible to launch our Rehearsal Tests using version 3.6 of FireFox. Instead, please continue to use FireFox 3.5.7 or Internet Explorer 7/8. To prevent FireFox from automatically updating click on Tools > Options. Then, click Advanced and select the Update tab. Select ‘Ask me what I want to do’ below the part saying When updates to Firefox are found:’ as shown below. If you have already updated FireFox and wish to return to FireFox 3.5.7 please visit this link. We are working to resolve the issue and appreciate your patience while we do so.
