Attachment: GSlides 2017-02-06 5.42.23.png

+++ This bug was initially created as a clone of Bug #1331737 +++

STR:
1. In Firefox Nightly, open a Google Slides such as:
https://docs.google.com/presentation/d/10P0gEtg67XcPm5nXgp5E2bw_mi35k2ceBs2C2fMQvI0/edit#slide=id.g13e9e97e33_0_0
2. Wait about five seconds for the doc to finish loading.

RESULT:
Google Slides shows a warning that says "Some fonts could not be loaded. Try reloading." I don't see any obvious errors in the devtools console.

I can reproduce this warning consistently with Nightly 54 (on Windows 10 and macOS 10.12), but not in Beta 52 or Release 51.

Bobby, this bug is probably a duplicate of bug 1331737. Look in the Firefox *browser* console, not the *devtools* console, for warnings like these:

downloadable font: Layout: DFLT script doesn't satisfy the spec. DefaultLangSys is NULL (font-family: "Varela Round--Menu" style:normal weight:normal stretch:normal src index:0) source: https://fonts.gstatic.com/s/varelaround/v8/APH4jr0uSos5wiut5cpjrkWnNVpw0CtxFlw7ZW7Wg4I.woff2 (unknown)

To open the browser console, use Ctrl+Shift+J or the Tools > Web Developer > Browser Console menu.

If you see any warnings about fonts *other than* "Varela Round--Menu", "Alegreya Sans", "Amatic SC--Menu" or "Merriweather--Menu", then you have found a new bad font for Google to fix.

Note that Jonathan is adding a pref in bug 1331737 to allow us to disable the font checks so we don't see these Google warnings during our tests.

This is the same as bug 1331737.

Check the Browser Console (not Web Console), and force-reload the page; I think you'll see the error messages regarding the fonts there. Or disable the new web console front-end (devtools.webconsole.new-frontend-enabled = false) and re-open it.
