2 issues: 1. Firefox crashes every time I try to open QuickBooks online. I have submitted numerous crash reports. 2. When I click an email link on a web site, it opens a blank FF browser instead of an email program. I have set the default to Microsoft Outlook and also tried changing it to Gmail. Each time I click an email link on any web site, however, it just opens up a blank page instead of one of my email programs.
