Can not reproduce the issue on neither Win10(19042.2965) / Win11 (26100.7462) using Firefox builds 147.0/148.0b2.
Not sure if the issue reproduces with a new and empty profile? See https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile
Thank you.

Starting Firefox with a new profile solves the problem.
Then, if I launch Firefox from the command line with firefox.exe -P and choose the former profile, the bug does not occur. However, if I set the former profile as default and relaunch Firefox from the taskbar shortcut, without going through profile manager, the bug occurs.
The taskbar shortcut simply leads to C:\Program Files\Mozilla Firefox\firefox.exe, with no window size option selected.
It might be worth emphasizing a couple points from one of my details (see above):
My specific environment: Windows 10 Home ver. 10.0.19045, with the taskbar locked at the bottom.
- My Windows 10 (Home) version is more recent than the 19042.2965 used in the test that failed to reproduce the bug.
- Note the with the taskbar locked at the bottom part -- might this be a relevant factor?
Also, when the bug manifests, do we know whether the Firefox title bar is actually absent or whether the window is too tall and pushes it offscreen?

This has been happening to me as well I have to right-click the menu bar area and select "Customize Toolbar" and then toggle the "Title Bar" box to restore it.

By "toggle" you mean change the value from what to what? Having "Title Bar" in the checked state does not work for me. How about the other factors I mentioned -- do you launch from a shortcut with "Run: Maximized" and is your Windows taskbar locked at screen's bottom? And you're on the same Windows 10 build?

By toggle, I mean when I goto Customize, the option for "Title Bar" is already checked, I uncheck it, then re-check it and the title bar is back.
When I launch FirexFox its from a desktop shortcut which is Maximized by default.
I'm on Windows 10 x64 22H2.

I see. If that doesn't result in a "permanent" fix for you, it might be easier to press F11 twice after startup, which works (temporarily) for me and others with this issue.
How about your Windows taskbar -- locked at the bottom of the screen?

Until I came here, I didn't know about the F11 trick. :)
