Unable to change interface language to Norsk Bokmål (Norwegian)

[nilsfr]

What happened?

When I change the language to Norsk Bokmål under "Language and Appearance" nothing happens. The interface keeps the current translations. It looks like this only affects Norsk Bokmål, not other languages. If I, for instance, change to Nynorsk it works as expected. Norway have two written languages Norsk Bokmål (nb-NO) and Nynorsk (nn-NO).

I run Waterfox version 6.5.4 as a flatpak on Ubuntu Linux 24.04. My system language locale is nb_NO.UTF-8.

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.
