After the last update (40.0.2 @ 13.08.2015) Firefox just wont open. The process comes visible in task manager, but does nothing. no window. JUST. NOTHING. It only functions in either safe mode or when ran as an administrator. I tried all other computers in the house too. Same thing.

How to fix?

Firefox 40.0.2 (problem does not occur on FF 39.0.3)


Any Firefox window has a colored vertical region (20-or-so pixels wide) beginning just under the system title bar and extending down to the bottom of the FF window. The region begins as a single color(1) but then, as the viewport changes(2) this region is segmented into sub-regions of independently varying colors. Multiple windows maintain their own independent colored region.

If multiple firefox windows are opened, each has its own region. Context menus (e.g. right clicking anywhere in the FF window) also have such a region. Disabling all extensions, plugins, and themes has no effect.

(1) The colors I've observed are always fundamental (cyan, magenta, yellow, green, blue, red, gray). When the color is set or changed (described below) the color seems to be set at random - that is to say I cannot distinguish a pattern as to how

(2) Scrolling the viewport or invoking a browser modal/prompt/file dialog will cause the entire region to change to one other color. Certain (I can't nail down the rhyme or reason) block-level changes to a page will cause a sub-region to appear, horizontally aligned with said block. Page-wide changes "reset" these sub regions. Animations on the page causing color changes (such as the fading in of a modal overlay div or the slow sliding up of the Firefox address bar when entering fullscreen) will cause rapid color change during the period of animation/transition. Blurring the Firefox window or using the PrintScreen button will also reset the entire region back to one color so I'm unable to get a screengrab of varying subregions.


Is this a problem with Firefox? Where should I file a bug report? Mozilla? Gnome? X? Mesa?

I've uninstalled, reinstalled, deleted all profiles, viewed and attempted every suggestion that was found via search engine. Firefox will only start with -P option and creation of new profile. Once closed, it will not open again using the profile just created. Any ideas as to what type of additional troubleshooting that is available. There are no crash reports or logs generated anywhere that can be found. Running on Windows 7 Professional.
