svg support in Mozilla and Opera?

Question

css

Hello. Please take a look and let me know what could be causing the issue.
This and this page do not display svg sprites in Mozilla and Opera in different versions.
Example: clip2net.com/s/3LjLnuw and clip2net.com/s/3LjLtgV
svg icons are displayed on the main page, but not on the internal ones and I can’t understand what is the reason, can you help))

Answer 1

SVG has nothing to do with it:
caniuse.com/#search=svg xs
, I only noticed that Yandex for symbol gives width height auto, and mozilla 0. But I still don’t understand what the hell

Answer 2

write<use xlink:href="remont/#icon-email"></use>
