Fixing LaTeX Not Working on Firefox 99

[carpinus]

hello,
I am trying to use latex in a thread, but for some reason it does not work, eg. v^a is displayed as v^a
I am using firefox browser version 99.
many thanks for your help

Let me try $v^a$

works for me

I used #.#.v^a.#.# without the dots. The double number signs cues Mathjax that there’s an expression in Latex to be rendered.

Theres a link to a latex tutorial below in my signature area.

Reply to this post to see what I posted.

For an inline equation $ax^2 + bx + c = 0$ and for a separate line $$ax^2 + bx + c = 0$$

sorry, I was unclear
I tried using the dollar or the hash sign from the beginning and they don't work

Why not post your Latex here?

Did you use single or double hashes?

I remember fixing a post in a thread that used single $ around a theta that was also missing a backslash.

$.theta.$ vs $.$.\theta.$.$

( remove the dots from the expressions to make them render correctly. )

There's also a link in the input pane every time you start a thread or write a response to one.

now it seems to work.
at the beginning some strange things happened.
e.g. it was as though I had to log out and log in again to get the code rendered.
at some point I used 'save draft' and 'delete draft'.
thank you very much for your advice

If you are the first writing LaTeX in a thread it will not render immediately. Try to reload the page in those cases.

When trying to demonstrate $\LaTeX$ in a thread, one can prevent the ## and $$ from rendering by using the little palette icon to select a color for one of the # signs or one of the $ signs.

So one can write that $\sqrt{2}$ is written as ##\sqrt{2}##

Edit: The pallete icon gives you a friendly way to insert things like [COLOR=rgb(0,0,0)] into your text. Those BB code tags get in the way of the MathJax tags and prevent them from rendering.

Edit 2: If you reply to this and use the [ ] icon to turn off BB code rendering, you can see what I did here.

Never thought of the coloring trick, that’s great!

That's exactly how I do it.

Yes indeed !

I picked up this trick from Mark long ago.
