I don't know, whether this is the right place to ask this technical question. So, moderators, please feel free to move it wherever it fits better. For some time I realized that, when I write a posting to the forum, it takes a pretty long time to render the equations. I don't precisely know, when this behavior occured the first time, but before rendering has been very quick. Is there something, I can install locally to make this faster? I'm using Mozilla Firefox as a browser, and I've installed the mathml fonts as a plugin, but this hasn't had any effect on the rendering of postings.
