User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:55.0) Gecko/20100101 Firefox/55.0 Build ID: 20170501100238 Steps to reproduce: Not 100% reproducible. But happens quite often. 1. Open Firefox 2. Maximize it's window 3. Close and re-open Firefox Actual results: Often the window maximization state is not restored, but instead the window have the same size as the maximized window would have. Expected results: The window maximization state should be restored every time based on in which state the window was before closing Firefox.
Which distro and DE do you run?
Debian (testing/buster) with xfce, but I've used Linux Mint with Cinnamon before and this issue was present even there.
