I have been desperately trying to get off Chrome and onto Firefox and I simply cannot. Over the past month I have tried at least a dozen times to install Firefox and migrate, to absolutely no avail whatsoever. Any time I "launch" Firefox, I simply get a flicker of a black (or sometimes white) window, and then nothing. Firefox immediately disappears off the taskbar after a mere flicker. It doesn't even show up in task manager during this process. The browser absolutely refuses to launch, period. I have tried uninstalling Chrome. I have tried reinstalling Firefox. I have tried restarting my PC. I have tried updating Windows. I have tried booting Firefox in Safe Mode. I have tried running Firefox as Administrator. There is no error message. There is no bug report. There is no Windows alert. I have scanned the PC for malware at least five times, it's completely clean. I've tried "refreshing" Firefox in the uninstall menu. I've looked through every existing support article known to man at least five times over. I've tried checking my antivirus software, and I've tried checking for files that can reportedly keep the browser from running, none of which I have on the PC. I have tried simply launching the damn browser more times than I can count. The result never changes or deviates from Firefox simply flickering for a nanosecond before crashing. Please help me find a way to just launch the browser.
