Yes, I've seen that on this site, where some sidebar sections expand after the initial page load, pushing the content down the page from where the "hash" or "bookmark" or "anchor" was located. I'm not aware of any workarounds, although I'd love to know of one. When I searched for bugs on file, I found one from 2011 about this, where it was characterized as a hard problem. When I think about it, suppose the page scrolls, how does Firefox know whether that is something is needs to correct for vs. something you caused to happen? Hmm...
