Regardless of which browser(s) you use how often do you patch them.  Do you maintain the extensions and restrict what is and isn't sync'd.  I sit down with Kenneth May of Swift Chip to discuss how we need to do a better job creating whitelist/blacklist on apps within the browser. Educate the end user on the vulnerabilities created by adding extensions or not relaunching the browser when updates are pending.  It is Cybersecurity month and I think you will find this episode will give you some serious food for thought.
