Details

+++ This bug was initially created as a clone of Bug #642851 +++

This bug is still present 10 years later. I currently run a three monitor setup with taskbar set on autohide in the left edge of the screen. A soon as I maximize any Firefox window it will go on top of the taskbar making it impossible to "summon" by hovering the cursor on it.
The behavior is not present with Windows third party taskbars (i.e. DisplayFusion or Nexus Dock).

So, again, if:

Windows taskbar is not at the bottom,
Taskbar auto-hide is enabled, and
Firefox window is maximized.

(Windows taskbar can be dragged to any of the four edges of the screen. Auto-hide feature reduces the taskbar to a line 2 pixels high or wide at that edge, and shows the full taskbar when the mouse hovers over it. Apparently Firefox assumes the taskbar is always at the bottom when auto-hide is enabled.)

Steps to reproduce:

Drag windows task bar to edge of screen other than the bottom edge.
(for example, the left edge).
Right click on task bar, click "Properties", enable "Auto-hide the taskbar".
("taskbar always on top" is also enabled)
Open a Firefox window and maximize it. (Click the one-window button next to
the close box in the titlebar.)

Actual Result:
You won't be able to make the taskbar unhide with your mouse.

Expected Result:
A maximized window should not cover hidden taskbars, no matter what edge of the screen they belong.

Other browsers/programs handle this correctly.

Speculation (as OP mentioned): Maybe FireFox assumes that an auto-hidden taskbar is always at the bottom edge of screen. Instead, it should determine where the taskbar is located.

Hoping it will be sorted out in development, meanwhile this is my workaround for people struggling with this issue: press Start and the taskbar will show together with the start menu (it will lose focus and disappear as soon as you go back to Firefox's maximized window). Alternatively (not viable for me) use third party taskbars,

What didn't work for me: AutoHotKey script to keep the taskbar always on top of other windows.

Ok, note that the original bug is in the wrong DOM and doesn't show FF version.
