This bug happens for me since fresh install on daily basis. I am experiencing it (Window suddenly vanishes into a fine strip, resizeable though, if you by luck detect the fine strip, OR Window just minimized into incomplete window (no correct header) the size of 10 x 100 mm).
I am experiencing it NOT ONLY with FireFox, but also Libre Office, Thunderbird windows. I am experiencing it SEVERAL TIMES ON DAILY BASIS. It affects usability, when you work and the window just vanish. It is unimaginable if you make presentation in front of public and this thing happens on promoted Ubuntu. I have not found out, what action leads to this bugs. I suspect something corrupt in windows management. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1311983 Title: firefox window suddenly resize to about 10x100 mm to upperleft screen corner Status in “firefox” package in Ubuntu: New Bug description: While browsing with Firefox, for UNKNOWN REASON, suddenly resize to about 10x100 mm aligned to upper left corner of the screen. Grabbing is not possible, resizing is possible using "Shift"+"Ctrl"+"Left Arrow" short cut. In other instance it suddenly maximize to whole screen, the left side is behind the unity dash column and can not be accessed by mouse / cursor. Resizing using "Shift"+"Ctrl"+"Left Arrow" is possible. Back to "normal" from there. What activities lead to this anormality is not clear to me.
