What would be the cause of seemingly unrelated crashes when Flash has been ruled out?

I started out assuming it was a Flash issue. I reverted to 10.3 and still happening. Thought it was an issue related to Waterfox. I uninstalled that and switched to Firefox. I have a maximum of 5 tabs open and crashes are occurring regardless of what webpages are in the Tabs. Following are the reports.
