I was browsing a while ago on youtube, I saw it shows an insecure connection even though it was over https.
I'm using ghostery and adblock to block trackers but nothing more, I don't think it's the reason because I always blocked trackers and this never happened to me before. I don't know if it is a bug or something. I tried to inspect the page with the dev tools in chrome, but didn't see anything rare, just that it's a valid certificate but no https connection
it didn't matter if go back to the main page, chrome was still showing non secure connection
of course when I close and re-open youtube the problem was gone.
Is this something insecure for cookies or they can never be sent in this case if they have an https only flag?
