Attachment: languages.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3189.0 Safari/537.36

Steps to reproduce:

When first start firefox(you could delete .mozilla files), you will find some pages can not display chinese in Chinese OS environment

1. Firefox Privacy Notice---the page will open with firefox first start.
2. open about:Preferences --> Languages -->select "Choose your preferred language for displaying pages"
   Only en-Us and en for you choice, and not have zh-CN. etc

Actual results:

Open about:config and you will find intl.accept_languages="en-US, en"
but, when you closed firefox and open again, firefox will be display chinese normally, and intl.accept_languages="zh-CN,zh,zh-TW,zh-HK,en-US, en"

I test firefox71 on linux-x86 and linux-mips64, there are all such problems,
but test firefox60, it could display chinese when first start, No second opening is required to display correctlly.

I upload some pictures to show this question.

Expected results:

pages could be display chinese in Chinese OS environment when firefox first start.

If not delete "chrome://global/locale/intl.properties" from a basic
StringBundle implementation using shared memory maps, will lead to
many prefNames value not correct when firefox first start. such as:
general.useragent.locale
intl.accept_languages
font.language.group
intl.menuitems.insertseparatorbeforeaccesskeys

Depends on D45620

(Almost) same problem here with Firefox 68.1.0esr (64Bit) on a german openSUSE Leap 15.0 system. ("Almost" because the problem persists even after restarting firefox.)

After the update to FF 68.1.0esr pages like google-news displayed english content.
about:config shows intl.accept_languages = "en-US, en"
In about:preferences -> preferred language -> Button "Choose..." there is no "german" available, only [en-US] and [en].

I then started firefox with -P and created a clean new profile, but same behavior as before.

Regards,
Chris

I'd prefer not to invest in further improvements to StringBundle, and we didn't hear back from the reporter. I'm going to close it as inactive. Reopen if needed.
