I, too, was concerned that somebody might steal my password here since the site was HTTP only. Never mind that nobody would care to do that, as Etaoin Shrdlu noted; it's the principle of the thing! And besides, by entering our passwords via HTTP here, we foster a bad habit and may repeat the act somewhere more sensitive.
I'm pleased to note that for the last few weeks, or maybe months, I don't know since when, latindiscussion.com HAS added HTTPS, although they continue to provide HTTP as well. People who used the "HTTPS Everywhere" add-on that R. Seltza recommended probably were shifted over to HTTPS automatically. I wasn't, since I don't use it.
I'd like to make a couple of further suggestions.
1. On (secure)
http://latindiscussion.com/forum/ . This can easily be fixed either by changing "http:" to "https:" in the destination, or by simply removing the "http:" (since the protocol of the destination will default to the protocol of the page as being viewed). Alternatively, you could disable the HTTP service altogether.
2. If the Forum has been shelling out money to purchase the certificate for HTTPS, the Forum could reduce future expenses by getting a free certificate. I can look up the details about this, if desired.
One further comment (just a comment, not a suggestion, since I don't know what to do about it). Although I have an HTTPS (secure) connection to latindiscussion.com, Firefox warns me that there is mixed (secure + insecure) content. "A gray padlock with an orange or yellow triangle indicates that Firefox is not blocking insecure passive content, such as images. By default, Firefox does not block mixed passive content; you will simply see a warning that the page isn't fully secure. Attackers may be able to manipulate parts of the page like displaying misleading or inappropriate content, but they should not be able to steal your personal data from the site. " (
Mixed content blocking in Firefox )
My interpretation of that is, it is theoretically possible that any image I view on this site has been maliciously placed. I don't know how or where the images are stored for this site, but at present, I'm not intending to lose sleep over it. (I lose enough sleep already.
