I accidentally turned off MathJax on a comment so I could see the LaTex source, and I don't know how to turn it back on again. I turned it off by right clicking in my browser, but now when I right click, I get a Firefox menu instead of a MathJax menu. Please help!

    $\begingroup$ By switching of MathJax you mean that you have changed MathJax renderer to "Plain Source"? If yes, you can switch it back in the same way - just remember that to get into MathJax menu you need right click on some MathJax formula. See also: How do I change Math Renderer for MathJax? $\endgroup$ – Martin Sleziak Mar 3 '20 at 16:38
  • $\begingroup$ Yes, probably. But, as I mentioned, the menu no longer appears to let me switch it back. $\endgroup$ – Jim L. Mar 3 '20 at 16:39

    $\begingroup$ Even if I change the renderer mode to Plain source, I still see the MathJax menu under right click. One thing you can try is delete the cookie mjx.menu for math.stackexchange.com and restart the browser. I believe that cookie is the one storing your preference of renderer.. $\endgroup$ – achille hui Mar 4 '20 at 9:48
  • $\begingroup$ Maybe I was right clicking on some text that wasn’t rendered with MathJax or something. I haven’t tried to reproduce the problem because there’s a menu item to show the source in a pop-up that works even better that changing the rendering. $\endgroup$ – Jim L. Mar 7 '20 at 16:09

Perhaps someone else will find this useful some day.

I noticed that, for a split second, MathJax was rendering type-set equations before it was rendering the source. I was able to very quickly reload the page with Cmd-R (on the Mac) while quickly right clicking. That gave me the menu I was missing.

Was this a coincidence? Perhaps. I was also trying bookmarklets from this web page, which indeed caused proper rendering, but did not seem to affect pages on this web site. It may also be the case that I was not right clicking exactly on top of the LaTex source.

  • $\begingroup$ No, it was on an uneditable comment from which I wanted to copy the LaTex. $\endgroup$ – Jim L. Mar 3 '20 at 21:39
