@Krasnaya: Are you sure TeX Gyre Termes Math is actually used? It does not seem to be the case on your screenshot...

If you have a Wikipedia account, you can set the CSS:
https://www.mediawiki.org/wiki/Extension:Math/advancedSettings#CSS_for_the_MathML_with_SVG_fallback_mode

You can also click the "Advanced" button in about:preferences#content to select the "Fonts For Mathematics" or use https://addons.mozilla.org/en-US/firefox/addon/mathml-font-settings/

Yes, I set the font face for MathML, but the problem is still there.

I opened https://fred-wang.github.io/x-tex/demo/ after that, all intergral symbols works fine to me. It seems to me that Wikipedia's server has a bug affect MathML rendering for contour intergral symbol.
