Hi there,
On some of machines I use, after opening of Firefox I get empty browser
window (with menus, decorations etc) but nothing else is displayed. Its
impossible to open menu, type address, etc. The only thing you can do is
to close the window. After changing display configuration (rotate to
portrait, adding external monitor..) it starts to work as expected. You
do not even need to reopen. Moreover, it looks that Firefox was running
ok all the time but nothing was displayed.
After recent updates on some machines I get the same problem using
firefox-esr.
The only error mesg I get is:
###!!! [Parent][RunMessage] Error: Channel closing: too late to
send/recv, messages will be lost
