When using the desktop version of Firefox (versions below 4, i.e., 3.6) the following regex (from Alpha 4.1) is causing Firefox to stop working:

pageElemRegex = new RegExp(".*(<[^>]+\\bdata-" + $.mobile.ns + "role=[\"']?page[\"']?[^>]*>).*"),

This only occurs on 'heavy' pages, i.e., pages that have a lot of elements to load, and script to work with. I tracked the problem back to the regex above, but I do not know what it does or how to fix it. Again, only seems to occur with Firefox 3.x. 

Anybody have some ideas on how to fix this? I really need firefox 3.6 support. The regex is the only issue... What is the regex above even doing? Any help or thoughts would be great!!!
