language issue

Applications with translations use the selected default language,
assumed it's available.

However, if you start Firefox and QupZilla in a terminal with

LANG=C firefox
LANG=C qupzilla

English is enforced. 

When Firefox and QupZilla are in Hebrew all apps with a Hebrew
translation should be in Hebrew. Some apps might be in English, because
they don't provide a Hebrew translation.

There are several ways the wanted language and area settings could be
selected.

If those settings are correct

and English still is ignored, you need to dig deeper
