OK, a few things here:

So does your script do something to/with the breadcrumbs?
If so, then in 2017r3 the breadcrumb links are no longer included at build time (in the HTML source), but are loaded dynamically by MadCap's scripts at run time. This means any scripts you run that affect the breadcrumb proxy (or menu proxy) will have to wait until the MadCap scripts have populated the links in the proxies. You do this by waiting for the the "loaded" event, before you run your own script.
See kb article:
http://kb.madcapsoftware.com/Content/Mi ... _Menus.htmThe examples are for the menu, but presumably the same technique can be used for breadcrumbs - if you're not sure, ask MadCap support.

Flare already includes its own copy of jQuery in the output, so that means you're now loading two copies (and different versions) of jQuery. Do not add your own version of jQuery.
