Mathjax doesn't works in Firefox 69.0.2 (Windows 8.1) #306

Let's say we have some test file:

= Test file
:nofooter:
:stem: latexmath

stem:[\sin(x^2)]

In browser we see the following:

It's okay. Please do nothing and wait for several seconds (approx 25 seconds).

You will see:

Please fix this and update mathjax version.

Unfortunately this error doesn't produce anything in devtools console. The only I found is:

TypeError: c.FONTDATA.FONTS.MathJax_Main[8212][5] is undefined

but this error is shown before math processing error.

Best regards,
Andrey.

The text was updated successfully, but these errors were encountered:

I found, what causes this error. But I was need to write video and make screenshot from video player, because error text was replaced by html page quickly:

I reinstalled extension and found a way to get error message:

Error: this.imgEmWidth is undefined

file: moz-extension://c6b73dec-c558-458d-808c-0d837a088a39/vendor/MathJax/jax/output/HTML-CSS/imageFonts.js?V=2.7.2
line: 19

Debugging tips: use 'unpacked/MathJax.js', inspect 'MathJax.Hub.lastError' in the browser console

Hm... It seems that Firefox blocks to load some files...

ggrossetie · 2019-10-07T17:04:17Z

Thanks for raising this issue and digging into it!
I believe this issue should belong to https://github.com/asciidoctor/asciidoctor-browser-extension right? Let's continue the discussion over there 😉

sindzicat · 2019-10-07T17:08:36Z

Yes, it's right. I'm about extension for Firefox.

sindzicat · 2019-10-07T17:12:37Z

The problem is that something blocks some MathJax files in Firefox. Any ideas to fix this?

ggrossetie · 2019-10-07T17:20:06Z

Firefox 68 introduced a strict security policy: https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/68#Security

Can you please try this procedure: #302 (comment) ?

sindzicat · 2019-10-07T17:22:26Z

privacy.file_unique_origin is false already. Sorry, this didn't help me.

sindzicat · 2019-10-07T17:29:12Z

By the means, I switched privacy.file_unique_origin to false, because include directive didn't work. I found you comment and made this change.

sindzicat · 2019-10-07T19:52:16Z

I found a workarround:

about:config
type policy in search field and wait for a few seconds
backup value of field extensions.webextensions.default-content-security-policy in text file.
copy value of field extensions.webextensions.base-content-security-policy to value of field extensions.webextensions.default-content-security-policy. In my case I copied script-src 'self' https://* moz-extension: blob: filesystem: 'unsafe-eval' 'unsafe-inline'; object-src 'self' https://* moz-extension: blob: filesystem:;

After these manipulations all works fine.

That means that problem is in content security policy. It seems to me you should edit extension manifest to fix this problem.

UPD: Sorry, this is NOT a workarround.

sindzicat · 2019-10-07T19:53:14Z

https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/content_security_policy

sindzicat · 2019-10-07T19:54:59Z

Just found (maybe, this will be usefull):

Firefox does not support 'http://127.0.0.1' or 'http://localhost' as script sources: they must be served over HTTPS.

sindzicat · 2019-10-08T06:27:17Z

Now I found what causes this problem.

Error preparing HTML-CSS output (preProcess)
File failed to load: moz-extension://a1ee119f-6f8c-4372-b219-7f46295a6157/vendor/MathJax/jax/output/HTML-CSS/imageFonts.js"

The first problem file is moz-extension://a1ee119f-6f8c-4372-b219-7f46295a6157/vendor/MathJax/fonts/HTML-CSS/TeX/png/imagedata.js I tried to open this link in Firefox and saw that there is no such file.

Then I found extension xpi file, copied it on Desktop and opened this file via 7zip as archive. I found that folder png is really missing in vendor/MathJax/fonts/HTML-CSS/TeX/. So this is definitely error of this extension.

Please update Mathjax to the latest 2.7.6 version and pack it correctly.

We do not include the whole MathJax distribution (33Mb).
The browser extension (without MathJax) is only a few Mb and I don't want to add more than 30Mb just for one feature.

Also, please note that the package hasn't changed in years and, as far as I know, it was working fine in Firefox 68 (and it's also working fine in Chrome). So something changed in Firefox.

Please update Mathjax to the latest 2.7.6 version and pack it correctly.

There's already an issue to upgrade to MathJax 2.7.6: #274

I will try to include the whole Mathjax distribution in extension to troubleshoot this issue on Firefox.

Surprisingly, Chrome extension doesn't have this file too. But log is difference slightly:

Loading [MathJax]/config/TeX-MML-AM_HTMLorMML.js
Loading [MathJax]/jax/output/HTML-CSS/jax.js
Loading [MathJax]/jax/output/HTML-CSS/fonts/TeX/fontdata.js
Loading web-font TeX/Math/Italic
Loading [MathJax]/jax/output/HTML-CSS/fonts/TeX/AMS/Regular/Main.js
Loading web-font TeX/Main/Regular"

So it's possible for MathJax to load web fonts in Chrome. That's why I see first error TypeError: c.FONTDATA.FONTS.MathJax_Main[8212][5] is undefined in Firefox.

According documentation this is an expected behavior. Hm...

I downloaded and installed MathJax fonts from here and restarted Firefox. This solved my problem.

Maybe you need to update documentation. Also it seems to me that such problem will not presented in MathJax 3.0.

@Mogztter, sorry, I didn't see your answer. You don't need to include full MathJax distro in extension. Just add in documentation, that Firefox users need install Mathjax font on their computers.

No worries.
MathJax should work out of the box, I will see what I can do to please Firefox 😉

Using MathJax 3+ seems to resolve this issue.

ggrossetie · 2019-10-12T11:45:46Z

I've just released and published version 2.3.0: https://github.com/asciidoctor/asciidoctor-browser-extension/releases/tag/v2.3.0
Could you please confirm that this issue is now resolved (using MathJax 3.0.0) ?

Also the rendering should be faster ⚡

sindzicat · 2019-10-13T16:24:03Z

Just tested in Firefox. All works fine! 👍 Many thanks!

Also, rendering is very fast now!

ggrossetie · 2019-10-13T17:16:14Z

I'm glad to hear that!
Thanks for your report 🧾
