Lots of sites (or at least the ones I look at) have MathJax math support. However, the default in just about every one seems to be to display as HTML/CSS, which simply does not work on any browser I've tried. Doing a right-click on an equation and selecting 'display as SVG' gives me the equations, but it's a pain having to do it for every site. Is there a way to tell the browser (via a user.css file or similar) to always display as SVG?
The MathJax site implies that it should be possible through web site config files, but all the documentation is addressed to people who are building web sites. I'm just viewing other people's sites.
