Details

(Whiteboard: [mac:multimonitor])

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_5) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.1.1 Safari/605.1.15

Steps to reproduce:

  • Open Firefox

Actual results:

  • Firefox launches at the main laptop display, ignoring the active external display.

This is present on macOS 10.15.5, tested under a MacBook Pro 2018, 13".

Expected results:

  • Firefox should've launched at the currently active display

This is also valid for all Firefox sub-windows, like History, About etc. They always use the main system display, ignoring external one.

I'm not sure what the expected behavior should be in this case, unfortunately even though I have a MacBook Pro, I do not have the external display to connect it to. I'm setting the component Widget: Cocoa so that someone with more experience in this area could take a look.

Component: Untriaged → Widget: Cocoa
Product: Firefox → Core

It should start at the screen the cursor is in (active screen).
