Note that this works if you use https://addons.mozilla.org/firefox/downloads/file/4267777/text_fragment-0.7.xpi, so it's definitely a problem with FF's implementation.

If I'm not mistaken, Wikipedia uses hidden=until found, which is not implemented in Gecko yet, see bug 1761043. I have implementing this feature and integrating it with Text Fragments on my roadmap and will come back to this.
