So. Run into this issue many times before. Your comic itself is only http: not https:
Comicfury is an https: because it needs to be secure for passwords and such.
When you share the link, assuming you've copied and pasted it'll be http:
However, some browsers, Firefox especially, will freak out and change it to https: when someone clicks on it, which your comic is not so it freaks out again with the message. It's not something that can necessarily be fixed from your end
At least this is what I've deduced from multiple instances.
SunnySideUpSmile:9. @JoshuaStern, I love it so far! Problem: I think it seems to be a little cliche. Ruby is in the forest. Ruby sees a bear, tries to leave, trips, and gets lost. She gets stuck in a trap, and a wolf chances upon her. I mean, don't get me wrong, I love it, but maybe you could space out the bad things a little? :)
I agree that Ruby is having a lot of bad luck constantly throughout the first pages -- she even comments on it -- but I found it the most efficient way to lead up to what comes up in the future. Believe me when I say I went through maybe five different ways I could have introduced the comic, and this was the start that made the most sense without becoming a horrendously long chapter.
But don't worry, I have a ton of good stuff ready for the lovely Ruby.
