Google rolled out the option to “always use https” — encrypting your mail as it travels between your web browser and our servers. Using https helps protect data from being snooped by third parties, such as in public wifi hotspots. “If you’ve previously set your own https preference from Gmail Settings, nothing will change for your account. If you trust the security of your network and don’t want default https turned on for performance reasons, you can turn it off at any time by choosing “Don’t always use https” from the Settings menu. Gmail will still always encrypt the login page to protect your password. Google Apps users whose admins have not already defaulted their entire domains to https will have the same option,” stated Gmail blog. To disable this feature, go to Gmail’s settings page, select “Don’t always use https” and click on “Save changes”. If you can’t use Gmail offline when this feature is enabled, try this workaround.
