How to re-enable warnings about insecure HTTP(S) contents in Firefox 19?
Firefox 19 seems to have dropped the warnings about insecure HTTP(S) contents, i.e. warn about submitting form data over HTTP (no S!), mixed secure and insecure contents, leaving a HTTPS page and so on. How can I get these warnings back? Or are there now different warning mechanisms (e.g. showing an insecure form submission in adance, that means at the time of filling it in)?
Additional System Details
- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:19.0) Gecko/20100101 Firefox/19.0
Those warnings are gone, so you can't restore them.
- bug 799009 - Remove support for obsolete SSL-related warning prompts
Warning, you are about to enter a secure site Warning, you are about to leave a secure site Warning, you are about to submit a form to an insecure site, when you are already on an insecure site. Warning, you are viewing a site with mixed content.
firefox will now allow you to block active mixed content though - enter about:config into the firefox location bar (confirm the info message in case it shows up) & search for the preference named security.mixed_content.block_active_content. double-click it and change its value to true.

OK, thanks a lot about the explanations, but in my opinion there are still two things open:
- Leaving a secure site. The former dialog did only inform one, but a prompt would be better, so that one can choose. Since you folks think it's outdated and I disagree the prompt could be disabled by default but security-aware people may enable it.
- Submitting form data to an insecure site. The warning at submit time is maybe too late, so why not show a symbol on the site before/while filling it in?
