Hi. was using firefox on my win 10 laptop. Yesterday a notification came up stating a windows update needs to be installed. Updated windows. after restart, firefox refuses to launch. On double clicking the icon, HDD light glows for few seconds, then goes out. firefox is not launched. CTRL+ALT+DEL shows task manager where firefox is shown as running in 32 bit. I havea 64 bit machine. ASUS S400C.

Downloaded and installed firefox again but problem persists.

Tried to launch profile settings from command prompt but it does not launch.

Please Help. I do not want to loose saved passwords.

Since there can be a handful of issues as to why Firefox doesn't launch, I recommend investigating [|THIS DEBUG ARTICLE] made by them. Should help you sort out your problem.
