Since the Firefox (and x64 variant Cyberfox) update to v39, gmail keeps forcing links to http(s), thus not opening, even though with Yahoo mail or my ISP (Outlook) mail they open http. I googled the problem and viewed my gmail settings but cannot figure out how to stop this behavior. It may have something to do with Sandboxie, Norton IS or Malwarebytes Premium and google but not the other mails. I disabled Adblock Plus too. Appreciate your help as always!
Gmail should normally always use HTTPS? I'm guessing it's either a problem with the browser or Norton IS. Also try to clean your cache and cookies.
No! If you try going to any site that is listed in an email, it renders https even though any other browser http. e.g. In an email from PC World this link was included: https://mail.google.com/_/scs/mail-.../t=zcms/rs=AHGWq9AKb7cbNT5VTJuCO-7pzlj9H3q7Xw But it won't open. Just the tab renders!
