Did you take a screen of the error in FF?

Have a look at the link:

https://codepen.io/Wpitallo/debug/dmOvjO

You will see the SVG in chrome and not firefox

So is there a reason you are showing the errors and not fixing them ?

I am showing you as there are no errors.

That error is a codepen issue, there are no other validation issues with the error that I am showing you.

get rid of this color="#111" it will work fine, you can define color there

Please let us know if this solved your issue or if need further assistance.

Sorry, ignore that error, that is an error with codepen. That has nothing to do with the error that I am illustrating.

If you open this link in chrome you will see an animated svg, in firefox nothing:

it has nothing to do with color="#111"

I tried the image with base64 encoding and that works for me, so this might be an issue with "#" symbols in the code that are known to cause issues with data URIs.
