I've always logged in hotmail with this browser, now that I've updated it tells me that Firefox can't log-in because the site is untrusted. Come on guys I've never had a problem before what gives here. Are we having the same problem between Firefox & Microsoft like were having with Kaspersky & Firefox. please communicate with each other. When you get an update ready for the consumer make sure that it will work with other programs & add-on. just updated v9 something and I lost my virtual keyboard and tw other ad-on. Furthermore, I was also able to sign in my gmail & yahoo account, no problem there.
