User Agent: Mozilla/5.0 (X11; Linux i686; rv:25.0) Gecko/20100101 Firefox/25.0 (Beta/Release) Build ID: 20131112160018 Steps to reproduce: I browsed to http://www.canonical.org/~paulv/emoji.html. Actual results: On Android 4.4 (Nexus 7 2013), using Firefox 25.0.1 and Firefox Beta, downloaded from the Google Play Store, the line with the utf-8/emoji is rendered incorrectly. On Android 4.3 (Nexus 7 2013), using Firefox 25.0.1, the line with the utf-8/emoji was rendered correctly (I upgraded the device, so I can't test it in 4.3). On Android 4.1.2 (Samsung Galaxy S3), using Firefox 25.0.1, the line with the utf-8/emoji is rendered correctly. The bug is a bit odd. It seems to delete the previous characters on the line. View source on the page to see what the line should look like. Expected results: The page should render correctly.

I see this on my Nexus 5 as well (tested with Nightly 28.0).

Simple test-case: data:text/plain;charset=UTF8,%F0%9F%90%B1

Could you attach a screenshot showing the incorrect rendering, please?

I have the Nexus 7 2012 Android 4.4 "KitKat" /system/fonts/ folder at http://people.mozilla.org/~kbrosnan/tmp/944872/n7-2012-fonts.zip
Chrome doesn't get this test case right either, but it does manage to show the text that Firefox doesn't (But fails at the Emoji as well)

Hmm - looks like the 4.4 /system/fonts/ folder (from comment 5) includes Google's "Noto Color Emoji" font, which uses their new (and not standardized) format to embed color bitmaps. I suspect that's probably triggering the problem, although I'm not sure why - even if we can't render that font (which requires a pretty recent version of FreeType, at least), it shouldn't affect the rest of the text.

Support for the color emoji font is bug 974575 and bug 969814. I believe the other missing (non-emoji) text was bug 973380, which should now be fixed on trunk.
