Location of Firefox throbber/spinner image

Question

I'm trying to locate the "throbber" (or "spinner") image used in the Firefox 3.6x chrome to show that a request is being processed:

I'm not familiar with the source code structure for Firefox, and a simple search hasn't yielded the answer.

Does anyone know which file I'm looking for? (E.g. can you provide a link to the file in the Mercurial repository, or tell me how to find it?).

Answer 1

Inside of your Firefox installation it's inside chrome/classic.jar, the path is: skin/classic/global/media/throbber.png

I'm not sure where it is in the Mozilla repository though.

Here's some info on how to customize it: http://kb.mozillazine.org/Throbber_URL
