Hi, I want to do firefox web extension to prevent redirect. F.e.: I wait urls like https://A, but when this A url load, it 302 redirect to https://B, and the extension don't run because we are on B url, not A. I don't know B url and it can be different each time. content_scripts.run_at.document_start wait until request is done and don't help. Can I resolve my problem with web extension? Or I must try other thing?
