Fonts are not loaded in Firefox

[Tobias Dörr]

Hi,

I think MathJax is just great and so I wanted to use it on a website.
But unfortunately it takes a lot of time to load in Firefox (almost
one minute)...

During this time, messages like "Loading Web-Font TeX/Math/Italic"
appear in the bottom left corner. I learned that this happens due to
Firefox's privacy policy which prevents MathJax from loading the web
fonts from a remote server... But I am using MathJax just on one
server.

That is how I include MathJax (in exampe.org/index.php):
<script type="text/javascript" src="wcf/js/mathjax/MathJax.js">

And the fonts are located at example.org/wcf/js/mathjax/fonts/HTML-CSS/
TeX/otf.

What am I doing wrong? In other browsers MathJax works great.

Thanks for any help...

It sounds like you are using MathJax v1.0.1a, but haven't updated the
fonts to handle the changes that Firefox made with version 3.6.13. See

http://www.mathjax.org/2010/12/11/news/update-for-firefox-3-6-13/

for details.

Wow, it seems to work now. Thanks a lot!

I'm having a similar problem to Tobias, but even with the font files replaced, the fonts are still loading very slowly, you can see at the test page:

That page loads fine for me. What version of Firefox are you using?
Which OS?

They work for me, too. But note that you are using v1.0.1, which does
not handle Firefox 4 beta properly, so if you are using FF4b, you
should update to MathJax v1.1-beta from the GitHub site. See the
download button at

https://github.com/mathjax/MathJax/

for the latest version.

Windows 7, Firefox 3.6.13

I had my wife also try it from her work machine--FF was noticeably
slower for her as well. :)

A few questions:

1. Is this page fast in all other browsers on those computers - IE,
Safari, Chrome?
2. When you say "loading very slowly", what sort of loading time are you
getting? 10 seconds, 1 minute, ...
3. After the page has loaded, can you type the following into the
address bar and report the message you receive:
javascript:alert(MathJax.Message.Log())

Worked as expected for me from Windows 7 with Firefox 3.6.13. The
fonts took about 2 seconds to load each. That is comparable to other
browsers I tested.

It sounds like your Firefox is still using the old fonts - empty the
browser cache and try again.

1. Other browsers are much faster--I can see the delay when MathJax
kicks in, but its brief. I even fired up IE (which hadn't used at all
today yet, so no caching and the like) it loaded the page and
displayed the equations in a few seconds.
2. In Firefox, it took 1 minute 23 seconds (stop-watch)...and that was
with a refresh, so most of it was cached.
3. I did. Looks like for each web font it follows this pattern:

Loading Web-Font TeX/Math/Italic
Can't load web font TeX/Math/Italic

On the off-chance Firefox was mental, I shut it down and back up and
tried again. No change.

I suppose if I'm the only one affected I'm less concerned, but its
interesting. :)

I'm sorry if you already covered this, but do you see the same behavior with other MathJax pages, i.e. fonts hosted on other servers?

--Robert

[Davide P. Cervone]

Have you by any change set the preferences to now allow the page to
set its own fonts? There is a preference for that, and it definitely
would cause this behavior.

Davide

[Iain Davis]

d'oh!

I should have tried that first. An obvious thing to try when having
problems with something web-based. :)

That, indeed, did fix the problem. My apologies for not trying it sooner. :)

I now have beautiful math formulas being delivered in my web pages!
Yay! That is, as soon as I write some. :)

My thanks, Sean and Davide.

Restarting Firefox doesn't empty the cache.
You need to use Tools > Clear Recent History (might be different on Windows)
