Firefox changes display language on Gmail "choose account" screen
I am located in Israel, but have set my default display language to English.
Over the past few weeks, when I go from the Google search page (my home screen in Firefox) to Gmail, the "select account" screen displays in Hebrew rather than English. Once I've selected an email account, however, the display reverts to English.
This is a minor annoyance, as I can easily navigate the Hebrew page, but it is a recent change, and I can find no explanation for it.
I have checked to see whether the problem occurs in another browser (Chrome) and it does not.
Any help would be appreciated
