I'm running centos 7. Firefox spends so much time in th D state that I am trying konqueror. Displaying mathematics on wikipedia, e.g. Remez algorithm seems to be a no go. Wikipedia seems to use tex, so I installed texlive and texlive-* . Firefox hadn't needed it and it did not seem to help konqueror. My guess is that there is a bit somewhere that I need to flip, but I have no idea where it is.
Suggestions?

Formulas can be composed with tex, but they're displayed as images. You shouldn't need any special browser support to display formulas. Can you post a screenshot somewhere?

Correct, they're just SVG images. In Firefox, if you type about:config in the search bar, you'll see several options starting with svg. They should all be set to the default (i.e., none should be in bold).

As one might suspect, it's on the NDSU CS department's server.
The web site seems to be emitting tex. Presumably something has to translate between tex and image. That said, firefox worked (barely) before I installed texlive.

It looks like you're using Konqueror, not Firefox.
The Tex you're seeing is alt-text for (what should be) the SVG images. I'm not sure how installing texlive would affect the browser.

Correct. That is what I wrote: On Sun, 17 Mar 2019, Michael Hennebry wrote:

That firefox worked at all on wikipedia mathematics was a reason I did not really expect texlive to help konqueror. Texlive was the only thing I could think of that made any sense.

Me neither, but I was low on things to try that made any sense. How do I get the SVG images?

Could it be a borked burntfox ( :-P ) profile. Try Private Window or a new profile and see if that fixes it. There was a time when I had one too many extensions causing all manner of mayhem
Cheers, ak.

SVG support in Konqueror is problematic:
https://www.hongkiat.com/blog/test-svg-format-browser-engines/ Konqueror is a default browser for KDE, one of the most popular Linux desktop environments. The ability to render SVG files in Konqueror depends on the rendering engine. With WebKit enabled our testing SVG was rendered correctly. However, Konqueror’s default rendering engine, KHTML, appears to be lacking support of several features: filter effects are not applied to underlying object and stroke end markers, and text along path or pattern objects aren’t rendered at all.
So you will need to figure out how to turn on WebKit which may not have been compiled in for that version. Rex Dieter had a copr with more modern versions of KDE for EL7 here: https://copr.fedorainfracloud.org/coprs/rdieter/kde4/
