I run firefox with the following command:
firejail --x11=xephy firefox The command usually opens a firefox window (800x600) that fills the xephyr window (800x600). In this case, the following problems occur.
Problems:
- When I click on the hamburger menu, it shows the menu briefly appears and then quickly disappears.
- When I type "alt" the menu bar at top appears. Then when I type f, the file menu briefly appears then quickly disappears.
However, after I run the command, I can intentionally kill xephyr (by pressing alt-f4). When I run the command again, firefox starts in safe-mode. The firefox in safe-mode would open a window that is smaller than 800x600. In this case, the problem disappears
Somehow setting the height and width of the firefox command as below doesn't solve the problem.
firejail --x11=xephy firefox -width=700 -height=500 The window environment is debian 10 + jwm + xorg.
I start it by startx -- -nolisten local.
