How can I find out what part of my Firefox installation modifies my HTTP headers?

Using a tool that displays my headers for the corresponding request I can see my headers contain the following string:

Accept-Language: de,ar-SA;q=0.8,en-US;q=0.5,en;q=0.3

I want to find out how ar-SA got in there.

I don't know how you'd go about seeing what changed your HTTP headers specifically, but I do know where you set your preferred languages. In Preferences, go to the Language section:

Firefox Language Section

And then click on "Choose..." to see them:

Firefox Preferred Languages Menu

I added "Dutch [nl]" to mine to see if my headers would change and sure enough they did:

Accept-Language: nl,en-GB;q=0.7,en;q=0.3
  • Thanks, this answers how I can see my preferences and indeed ar-SA is in there. However I'd like to know how it got in there! – Robert Norden Nov 26 '19 at 05:06
