Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:145.0) Gecko/20100101 Firefox/145.0

Steps to reproduce:

  1. Windows 11, Firefox >= 145.0 up to at least nightly 147.0a1 2025-11-12
  2. Have 2 monitors, one set to 150% scaling (main, 2880x1800), one to 100% scaling (secondary, 1920x1080)
  3. Maximize Firefox one of the monitors with multiple tabs open
  4. Position the mouse on the top row of the screen and try to click a different tab

Actual results:

When maximized on the secondary monitor, the tab isn't clickable on the top row of the screen. I have to move the mouse ~3 pixels down to be able to click it.

It functions as expected when on the main monitor.

Changing both monitors to the same scaling then restarting Firefox resolves the issue.

Expected results:

Tabs should be clickable on the top row of the maximized window.

This is the behavior on 144.0.2.
