Firefox miscalculates top edge in Windows 11

Sometimes, Firefox launches with its title bar just off screen (and the menu bar sits against the top edge) so the mouse cannot reach the title bar controls. I find that if I drag the right edge of the window in a small amount, the title bar drops down a few pixels so I can see a few pixels of the title bar and its controls. So adjusting the right edge seems to cause a recalculation of the top edge. It suggests that on launch, there is a miscalculation. It would be nice to fix this - a minor irritation as I now have a workaround. Note - if I *drag* the title bar to the top of the window, the furthest 'north' I can go is this same position with a few pixels of the title bar showing - If I go further, the title bar ( not the whole window) jumps back to have this same part showing. regards Gareth HP Envy Win 11 NVidia HDR screen 3840x2160 (the recommended setting) with text set 200%

Does it still happen in Troubleshoot Mode?

Interesting thought - but as it is intermittent, I'll have to run permanently in TS mode in the hope it happens, or not.

Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
