It seems this is the reason Firefox is saying "Parts of this page are insecure"!
Checking, at random, an old post on my SeaHawk forum:
https://forum.seahawk17.org.uk/Local-anchorage-td4025001.html I find a total of 13 matches for "http:"
That may be more than the average as I have implemented the Previous/Next topic add-on within the Gallery app that post appears in. But another result is:
Re: BUG: "Sent from http://forum.mysite.com" footer
I fear there is some misunderstanding on my part in this. When I say there 13 http: links on the page I am including all those to external sites, (such as the Social Media links) where I guess it doesn't matter and they won't be identified as a security problem in Firefox. But I do suspect that all the internal links to http://forum.seahawk17.org.uk are causing the problem.
As mentioned earlier, the first two of these are in the Previous/Next Topic links
<div class="root-text" style="margin:6em 0 2em;text-align:center;clear:both">

The last http: link is in the footer
<td class="footer-left weak-color">
<a href="http://www.nabble.com/" target="_top">Free forum by Nabble</a>
where it's probably the only link that should be insecure (non-SSL).
