Status: RESOLVED DUPLICATE of bug 1629291

(Core :: Widget: Cocoa, defect)

Description

[gary]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

Started Firefox day after I updated to 75.0 (64-bit) on my MacBook Pro OSX 10.9.5 and the menubar at the top was gone.
If I click and drag the cursor along the bar, various menu items drop down, some complete and others empty. Therr are no menu item titles in

Actual results:

It updated, later I shut down. On restarting the menubar at the top was gone.
If I click and drag the cursor along, the lowers some items but no item titles show. There are no labels in the menubar but some show dropped-down items.
I don't know where to go to find the menu items without searching by click and dragging across the blank bar (after the word "Firefox" next to the Black Apple.

Expected results:

All menubar items showing at all times with appropriate item showing when selected.

I'm going to dupe this against bug 1629291. There are a few workaround to fix the issue described there.
