As for IE vs. Chrome... I have two browsers usually installed on all computers, but when I deal with Microsoft sites (WinUpdate, MSDN, TechNet), I use IE exclusively. Years ago, it was a requirement and I haven't tried WinUpdate thru non-IE browsers lately).
But I use Firefox, Chrome, Opera and I'm trying out Comodo-Chrome now.
I really like Firefox most of all. It has a wonderful setting "Security" submenu where I can elect to clear off all kinds of cookies as "when I close Firefox". Nothing else gives me that kind of cookie-control.
For example, I don't save Passwords ever, but I like saving UserIDs. Firefox lets me do that while nothing else is saved (Save Forms but delete all other histories).
I don't prefer Chrome - it's too stripped down and doesn't give me 'enough control', and the lack of an easy way for me to tailor "bookmark sub-menus" irritates me. But I'm going to use this Comodo version along with Comodo's AV-Firewall for test purposes. I have customers and friends who constantly walk into Ransomware sites and then complain that it takes us two days to reload and recover everything for them. I'm hoping Comodo's stuff will be The Answer... although I know "without user discipline, no, nothing solves THAT problem."
I used to love Opera because it had a No-Frames version. No steenkin' animations, no steenkin' banner pop-ups. Just straight text - Read It and Move On. But of course, they had to jump on the All Glitz-No Substance bandwagon too... sigh...
