And then as soon as I launch it it keeps.
I then proceed to restart my PC and then install it from Mozilla's site. I uninstalled the Nightly version I had (it was outdated and I wanted to start fresh). So after leaving Firefox a while ago and now deciding to give it a go again. Or use a free online crawler like SSL-check or Missing Padlock, a desktop crawler like HTTPSChecker, or a CLI tool like mcdetect to check your website recursively and find links to insecure content. If playback doesnt begin shortly, try restarting your device. Keeping getting insecure connection warnings when going to any site. In any case, the best way to know if something is broken in Firefox is to download the latest Firefox Edition, open different pages on your website with the web console open (enable the "Security" messages) and see if anything related to mixed content is reported. Note that since mixed content blocking already happens in Chrome and Internet Explorer, it is very likely that if your website works in both of these browsers, it will work equally well in Firefox with mixed content blocking. There is no option to add a security exception to bypass this type of error. If I temporarily allow insecure connections on the web server, Firefox will then. A Secure Connection Failed error page will include a description of the error, an option to report the error to Mozilla and a Try Again button. It refuses to trust your OSs cert store, precisely because its so easy to simply install a fake CA into it and start MITMing peoples connections. Passive mixed content is displayed by default, but users can set a preference to block this type of content, as well. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. FireFox is the only mainstream web browser that is paranoid. Consequently, your website may appear broken to users (if iframes or plugins don't load, etc.). If your website delivers HTTPS pages, all active mixed content delivered via HTTP on this pages will be blocked by default.
