runpunkrun - re the yellow caution sign on firefox. That happens to me on all the pages I have images from photobucket appearing on. That could be a tiny icon, a background image, a mood theme, not just an image I've included in an entry. Basically the Dreamwidth content is all secure but the images I have hosted on photobucket are not (I note photobucket do not use https encryption). If I block images with my ImageBlock extension & refresh the page, the yellow caution sign disappears, which proves the hosted images are the culprit. As for the implications of this, this article may be helpful: https://support.mozilla.org/t5/Protect-your-privacy/Mixed-content-blocking-in-Firefox/ta-p/10990
