User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0 (Beta/Release) Build ID: 20130624104218 Steps to reproduce: On Linux, start Firefox. Actual results: The window shows up in the topleft corner of the screen, then after a second or so moves to the user's last window position. Expected results: Do not show the window until it has been correctly moved. You're probably asking the window manager to show() it too soon. This issue has been bugging me for years, kinda surprised there was no bug report about it :) This has been the case on any window manager: compiz, metacity, mutter/gnome-shell, ...
Could you please try the following, to see if you still reproduce the issue : 1) try this with a clean profile: http://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles 2) running in Safe mode: http://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Still happens to this day, on every version of Firefox that ever existed on Linux (including the latest with the much improved startup times), whether on Xorg or using Wayland (GNOME Shell).
