Re: Count me in.
My HP 1920 switches GUI works fine in IE but doesn't work in Firefox (never tried in Chrome as I don't want it near any of my machines). Firefox made its best to kill old sites but sometimes those "sites" are your devices interface, and cannot be upgraded easily. That's also true for some older Dell iDRAC application on older servers we still use for development and test. You can't upgrade hw at the same pace they deliver new browser versions - and not everybody needs a browser just for Facebook or Amazon.
The lack of backward compatibility, and the need to keep some old "portable" version at hand is becoming uncomfortable.
