Firefox not remembering window position in windows 10
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0 Build ID: 20180920131237 Steps to reproduce: Position and resize firefox. Close firefox. Actual results: When you reopen firefox, the window position moves up a few pixels. Expected results: It should have opened in the same location that it was closed in (previous behavior).
Note: Only noticed when I maximize the height of the window against the top of the screen. Upon reopening, the top of the firefox window is beyond the top edge of the desktop.
Can you confirm that this is still an issue if you update to Firefox 62.0.2? There were a couple of related bugs resolved in that release (1489214 and 1489852).
I can reproduce on Firefox62.0.2: 1. SNAP ON from Windows10 settings (this settings seems to trigger the bug) 2. Open Firefox62.0.2 and change window sizemode to normal 3. Drag top border of the browser to top of screen edge, the browser window will fit to maximize in height automatically. 4. Quit and relaunch browser

Regressed by: e6c9581ba20e Florian Quèze — Bug 1489214 - Set the position of the early blank window with the screenX/Y attributes rather than with the left/top features to avoid broken CSS <-> device pixel conversions in mixed DPI environments, r=mconley.
