Bug Description

Symptom: Since updating to Firefox 59, the Firefox UI items will be English only. E.g. all items under Peferences. Switching from en_US to de does no longer work.

The Firefox packages firefox, firefox-locale-en, firefox-locale-de are installed. All 3 packages have been updated from 58.0.2 to 59.0 by the updater.

When still on Firefox 58.0.2, the following settings existed and made sure my Firefox UI was localied to German (de)
intl.locale.matchOS=true (boolean, default)
general.useragent.locale=de (string, default)

After the update to Firefox 59.0 the second parameter is no longer set. It is simply not present any longer in about:config.
Adding it and restarting Firefox 59 does not have any effect.
The UI will remain English only and the parameter is gone.

This affects both Firefox packages:
firefox 59.0+build5-0ubuntu0.16.04.1
firefox 59.0+build5-0ubuntu0.14.04.1

Ubuntu releases:
Ubuntu 16.04.4 32-bit
Ubuntu 14.04.5 32-bit

Actually, the root cause is something which Mozilla seems to have forgotten implementing in Firefox 59:

Starting with Firefox 59, the parameter which specifies your localized UI language setting is no longer general.useragent.locale, type string, but
intl.locale.requested, type string

Mozilla seems to have forgotten to implement an automatism which rewrites the pre-Firefox parameter
- general.useragent.locale=de # German as an example
+ intl.locale.requested=de

So the solution is adding intl.locale.requested manually in about:config and restarting Firefox 59.0.

Problem is, that some systems with ubuntu-defaults-it , ubuntu-defaults-zh-cn and ubuntu-defaults-baltix packages installed doesn't have line
intl.locale.requested=""
in /usr/lib/firefox/distribution/distribution.ini
