When I have mixed content (SSL and non-SSL on a https:// page), I would rather have a broken page than an insecure page.

Is there any way to disable the loading of non-SSL elements while on an https page?

this isn't really an issue the "non-secure" parts of a page are the static images ( logos etc. ) and have no reason to be encrypted. –  Lamar B Dec 13 '11 at 7:53

@LamarB: It can be an issue if one of the insecure elements is a <script>, a good target for MITM attacks. –  grawity Dec 13 '11 at 12:51
    
@grawity agreed, but if security is that big of an issue you should already have javascript disabled and selectively run the ones you need. –  Lamar B Dec 13 '11 at 19:11

@LamarB: Well, first, many stores and banking sites require JavaScript. But the point I was trying to make is that without SSL, an attacker could replace a modify a script which you do need, and you wouldn't know it. You'd be thinking, "all scripts except this one are blocked, I'm safe". –  grawity Dec 13 '11 at 20:04
    
it's exactly to confirm that "non-secure items are just logos" that i want an option to not load those. I don't need to see one store logo while i enter my credit card at checkout. But i'm sure as hell not buying there if i have to look at the source to see if it's really just the images and not the scripts. –  gcb Dec 13 '11 at 20:07

HTTPS everywhere by the EFF may suit your needs it only supports a limited number of sites though. For non-supported sites you may need to find another option. https://www.eff.org/https-everywhere

On internet explorer 9 there is a "block unsecured images with other unsecured content" and a "display mixed content" enable/disable/prompt settings that should also help. Haven't found these type of settings for chrome or firefox yet but I would suspect that firefox's about:config would have similar settings.

the 2nd paragraph is mostly my question :) but thanks for the https-everywhere link! didn't know about that. –  gcb Dec 14 '11 at 5:52

Set the values of both of these about:config items to true:

  • security.mixed_content.block_active_content
  • security.mixed_content.block_display_content
