In Firefox localized pages, fonts don't display these characters correctly: Ɓ ɓ Ƴ ƴ Ŋ ŋ Ɗ ɗ... they seem to be replaced by a locally Unicode available font as shown on this picture.

We should find a solution maybe by using more standard Unicode font or design these glyhs for the font that Mozilla is using on the website.
Thanks for the report.

Not a duplicate, Fulah is an African language  with a couple special unique glyphs, I think Open Sans doesn't support it at all, I am almost sure that fixing bug 776905 won't solve this one.

Four glyphs exactly (Extended Latin B)
Ɓ ɓ Ƴ ƴ Ŋ ŋ Ɗ ɗ
Still relevant.

Thanks for the workaround. But maybe a Sans Serif font would match Open Sans better. Also, I believe Mozilla should not use a font that don't support languages that are active like Fulah.
It is so easy for the creator of Open Sans to add Extended Latin glyphs!

Hey guys, good news! My favorite Japanese font family M+ has the missing glyphs and "M+ 2c light" could be a fine combination with Open Sans Light. See the attached screenshot. M+ is a free font, so we can borrow those glyphs. Do you wanna try it?
Actually the Mozilla Japan Web site ( had been using the M+ font family before replacing with a similar Web font.

Actually the current /ff/firefox/new/ page is an old version and Open Sans is no used. I think this fix is only for /ff/firefox/*/whatsnew/.

Open Sans is a very nice font but it lacks dozens of glyphs for non Western languages. It is a shame that Mozilla used such a limited font that does not cover most African languages. When we mean global, we mean more languages supported, don't we?
Thanks all
I don't know if there is Open Sans alternatives. We cannot cover all languages with one single font. Technically it might be possible, but think about Asian languages; Japanese, my mother tongue, has thousands of characters and the size of the original M+ font file is 1.5 MB. It's still a subset of all Japanese characters. Forcing users to download a 1.5 MB font file is not acceptable, right?

Luckily M+ is a free, good combination with Open Sans and it has many glyphs that are missing in Open Sans. Like Fulah, we can generate it's subset anytime to offer a great Web experience to everyone while reducing the bandwidth usage of users. It requires a little additional work but I believe it's a realistic approach.
FYI, the subset I have generated for Fulah is only 1.7 KB.
