I'm currently using EFF's HTTPS Everywhere plugin to favor HTTPS whenever it is available.
Due to a wrong Common Name being used for the Meta website certificate, the first connection is a bit funky: requires to disable the plugin, manually trust the certificate, then re-enable the plugin. Afterwards, the Meta is accessed through HTTPS flawlessly.
At least it was so until the recent StackExchange major updates bringing us the new profile etc. During about a week, I began to have CloudFlare error pages telling me the back-end certificate was wrong, but refreshing the page one or two times was sufficient to access the Meta website anyway. A bit dirty, but working.
Now when trying to access the Meta website through HTTPS my request is systematically rejected by a "403 Forbidden" raised by "cloudflare-nginx".
Am I the only one who feel quite uncomfortable to discuss best security practices through plain HTTP? While not perfect, at least it was working until now, why drop it?
I thought the general tendency was to move from HTTP toward HTTPS, not the other way around :( ...
