594994 - Get Add-ons option displays Japanese with Firefox en-GB 3.6.9 build if intl.accept_languages variable ends in ja

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[mlj]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2.9) Gecko/20100824 Firefox/3.6.9 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2.9) Gecko/20100824 Firefox/3.6.9 (.NET CLR 3.5.30729)

Just updated to 3.6.9 and discovered that with my historic setup the default add-on configuration displayed above Japanese language webpage (https://addons.mozilla.org/ja/firefox/) rather than https://addons.mozilla.org/en-US/firefox/

Very interesting especially if you do not have full Japanese fonts installed.

This feeds onto the Tools>Add-ons>Get Add-Ons which displays a Japanese subsite web page

Discovered that because I browse Japanese websites at some stage the variable intl.accept_languages had changed to read en-gb, en,ja in some previous version Firefox.

Changing the user pref of intl.accept_languages to default for the en-GB build (en-gb, en) resolves the issue.

I suspect the issue is because someone assummed that the last specified parameter in intl.accept_languages tends to point to default language
Would be much safer to use value of general.useragent.locale (eg en-GB)   

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2.9) Gecko/20100824 Firefox/3.6.9 (.NET CLR 3.5.30729)

Reproducible: Always

Steps to Reproduce:
1.intl.accept_languages change from default to read en-gb, en,ja
2.Try to the access new add-ons
3.
Actual Results:  
Display of subpage https://addons.mozilla.org/ja/firefox/ instead of 
https://addons.mozilla.org/en-US/firefox/ (note https://addons.mozilla.org/en/firefox/ or https://addons.mozilla.org/en-GB/firefox/ redirect to https://addons.mozilla.org/en-US/firefox/ and I suspect this applies to all english language versions

Expected Results:  
Display of subpage of https://addons.mozilla.org/en-US/firefox/
