@BananaSlug: (nice nick ;-) mixed display isn't too bad; the HTTPS session isn't automatically shot. Probably, an HTML e-mail had an img tag to some HTTP resource? Longer term, perhaps they can be proxied.
@Motoma: interesting, do you have a sample URL that only works over HTTP?
will this affect iframed web apps that load the files from another website?
eg:
a facebook canvas game takes it's files from a server and displays it to the user.
normally, in the debug console this would occur (but it will still pass normally:
Unsafe JavaScript attempt to access frame with URL http://apps.facebook.com/app_name/ from frame with URL http://anothersite.com. Domains, protocols and ports must match.
Isn't the answer to this, from the attacker's standpoint, to serve malicious scripts and other content from HTTPS sites? You can get CA-issued certs for free these days.
And about the default-block of mixed scripting in Chrome 14, I frequently get mixed scripting errors in Reader and maybe even in GMail. What happens in those cases? Maybe they should be blocked. I wish it would be possible just to strip the scripts.
@Larry: There are some bug fixes underway in Reader. If you get the infobar in Gmail, put a comment here on how to reproduce it and it'll get fixed.
Regarding the attacker's standpoint, the attacker doesn't have any control over where the scripts are loaded from. So getting https://www.evilscripts.com/ won't help the attacker defeat mixed scripting blocks.
Is the reason that Chrome will continue to allow insecure subframes because AdSense does not support HTTPS and blocking insecure subframes would break Google's revenue stream?
EricLaw: It seems that AdSense is based on a script loaded from Google which do not support HTTPS: https://www.google.com/adsense/support/bin/answer.py?answer=10528 Linking to this script using HTTP on a HTTPS site would be a mixed scripting attacks that would be blocked. You can see this for example if you visit LKML.

I get the mixed display issue in Gmail all the time...
Does this mean the entire HTTPS session is shot?
Hey that's great; now if only AdSense would start serving over HTTPS.
This happens a lot in Google Reader, too. Particularly when a feed embeds to a Youtube video.

YouTube videos are a common culprit. Please add HTTPS support to YouTube before releasing this feature.
@MevlinRam: Very true! I believe YouTube does now support HTTPS embedding.

Actually, the AdSense script URL seems to work via HTTPS now. But I can't really see any danger if there is no script inside the IFRAME.
