See below Reproducible: Always Steps to Reproduce: 1. Go to a page that provides https (like the link provided above). 2. Click a link that is normal http and in the security message click cancel. 3. Click another link and in the security message select continue loading. 4. Go back in the original page, try accessing those two sites. Actual Results: You cant access the first link you clicked and you dont have any option, while the other page loads immediately. Expected Results: I think the preferred way that would not cause trouble to the user (that either clicked accidentally cancel or didnt know what to choose) whould be to show every time this message. So that option "Do not ask again" is the only way to suppress it. But not in any case, blocking any site perpetually.
