Pages with secure connection are presented in the same way, for example, the website forums.comodo.com the flags that we are on a secure connection and other sites like yahoo, google, malwaretips … are also presented (which can induce the user Not to use the browser, after all, in browsers based on chromium code present the pages in HTTPS differently)
EDIT: Would this be a new browser behavior or error?
Shane, I told you about the godaddy email box would run extremely slow with the new version of Comodo. i found out if I use a UA spoofer add on and say I am using IE9 then I have no problems with slowness. So it might not be a Comodo issue but maybe an incompatibility issue with chrome 55. Not sure if that helps.
