FF 53.0.3(64BIT) disappeared

[JOE1901]

I was running FF on win 10 for about 3 weeks and in the morning it was GONE. I tried to find on desktop but could not. I could not even uninstall it from my computer. MS uninstalled could not find FF. I reinstalled and the computer is running very slow.I have turned off add-on and still does not help. It is crashing also. Getting tired of dealing with FF and its problems.

Not sure if this would help? Latest crashes are not reported in crash report.

Does the same thing occur if you launch the application in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode

Sure sounds to me like Win10 blew away Firefox or ?? ... and because you re-installed it... something in Windows is still messed up?

Could be an issue with Windows Defender.
