After updating to the newest version, I am getting a blank screen for several seconds before the browser loads up correctly. I have followed all steps to debug extensions, theme and hardware acceleration issues and even after uninstalling, removing my profile and reinstalling the problem will exist on a freshly untouched Firefox. Oddly if I load it up in Safe Mode, instead of showing a blank screen, the browser will simply take longer to load up, but the moment it opens, it is displayed correctly.
