Bootstrapped Firefox extension: how to capture navigation events before a page request? -


i'm building bootstrapped firefox extension using mozilla add-on sdk (not traditional xul addon other similar questions).

i'd capture navigation events before issue http requests.

i've been using pagemod.pagemod({contentscriptwhen: "start", onattach: my_code_here}) - however, triggers onattach after page loaded.

that reinforced sdk documentation:

contentscriptwhen = "start": load content scripts after document element inserted dom, before dom content has been loaded

on bootstrapped firefox extension, possible capture navigation events before page loads?

you can intercept, , handle, requests via sdk's system events: how handle every request in ff extension

you don't need pagemod, on firefox level, not per-tab level pagemod.
