"from using OS locale, to use browser UI locale."
How is the browser UI locale set/chosen? If based on OS locale settings, great!
However, if based on (I guess) downloaded version:
Does that mean that Firefox will now ignore *my* preferred OS-wide settings?
(e.g.: 24h clock, YYYY-MM-DD dates.)
And date/time displays would be inconsistent with the date&time in my OS task
bar and most other software.
I would understand if Firefox offered a way to override that (which would be
useful for testing IIUC), but making it the default seems disrespectful of our
users.
