I have a website that do xhr that will result in file download. FF open new tabl for that filedownload, and XHR request will not be shown on network tab on original page.
How can I get request info for that xhr (best if I could get file download as response, so that I get both request and response info)?
Here is what I found that would force FF to keep file download connection in current tab:
about:config
browser.link.open_newwindow when set to 1 will do just that.
With it, download http request shows up normally in developers tools.
