Site Crashing FireFox

When you load it in Safari it also says ‘loading aborted’; the difference is that you can still see the page. Checking the source code I see your page contains so much non relevant code I’m not surprised it doesn’t load properly. Checking it with http://tools.pingdom.com shows the following:

Total loading time: 21.5 seconds, Total objects: 107 (1054.2 KB). So you have to load about 1 MB before the page has loaded..

I don’t know what it might be, but you could try removing things that aren’t really necessary. Maybe disable one plugin at a time to see if a plugin is causing an issue.
