Status: RESOLVED DUPLICATE of bug 1592416

(Firefox :: Menus, defect)

Description

[David]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

I am running macOS 10.15.2 / Firefox 71.0;

1. Make sure you have multiple virtual desktops opened (mission control)
2. Go to "Desktop 1" and open Firefox (i used a new/clean profile)
3. Right click the opened Firefox icon in the Dock, and choose "Options - Assign to -> This Desktop"
4. Now maximize the Firefox window by clicking on the green dot to enter full screen (this will move Firefox to Desktop 2 or 3 or above)
5. Now, if you right click in any webpage, the context menu that should pop up (the one that contains "save page as" etc), will not appear, as if the right mouse button is not working. Also, if you left click any folder in the bookmark toolbar, the popup window with the items in that folder will not appear.

To show what's going on: in step #5 when you right click (and the popup window does not show up), open Mission Control (in my case it's swiping up with 3 fingers on the trackpad) to show the overview of all the desktops, and you will see that while Firefox is opened Fullscreen in Window 2+, the right-click context menu is opened in Window 1 which we assigned Firefox to in step #3.
