Hi,
I got insecure content blocked by Opera browser and Comodo Dragon on Comodo Forum
Please see
Are there still http contents on Comodo Forum? Can someone check the emojis urls?
I cannot see emojis while starting a new topic or replying a topic.
Can anyone tell me what happen?
I think they changed the way to add emoji and links.
Now you can add a url by just copy/paste it. The same for emoji, you can just type “:” + “)” to get this 
Your website
Administrators have been informed regarding emojis.
Dennis
Thanks Dennis
Press Ctrl+Shift+I and click on Console to see all insecure content.
The problem seems solved. No alert now
Not yet solved for smileys.

This request has been blocked; the content must be served over HTTPS.
The alert is gone. I did not check that deep 
Comodo should serve all over HTTPS
You get a warning only for active insecure content (e.g. JS, CSS) that is blocked. By default, passive insecure content is not blocked, but the browser’s security indicator changes.
Can Comodo fix these emojis? Can you please make them HTTPS, as well ?
