I cannot clear Firefox history

Asked By 20 points N/A Posted on -

The error message I get when I try to clear Firefox history is: “Initialize in QuickTime has failed. ”  This prevents us from clearing our Firefox history and is annoying more than anything.

They don’t work what I have read lots of different things on the net such as do this do that, it is very simple to fix.

To get you up and running follow my 5 minute guide. I would request a right solution.

error #0

QuickTime Unavailable

QuickTime failed to initialize. Error #0.

Please make sure QuickTime is properly installed on this computer.

Hi there Abraham Adams,

I have some solution to fix that issue :

First option – Uninstalling Quicktime Program

Go to Start > Control Panel > Add or Remove Programs > Chooses Quicktime program then click Uninstall > restart your computer.

Second option – Reset MIME Types

1. Close Firefox > Go to C:Program FilesMozilla Firefox > delete “npqtplugin*.dll” files (npqtplugin.dll, npqtplugin2.dll, etc.)

2. Go to Quicktime plugins folder (C:Program FilesQuickTimePlugins) also delete “npqtplugin*.dll”

3. Go to Start > Control Panel > Quicktime > Quick Preferences windows will show up > go to Browser tab > Click MIME Setting, MIME Types window will show up > uncheck all MIME Types > click OK than OK again to close Quick Preferences window


browser streaming


Third option – Check if Firefox program is set to Compatibility Mode

Right Click on Mozilla Firefox icon on your computer desktop > Mozilla Firefox properties window will show up > go to Compatibility tab > Make sure “Run this program in compatibility mode for :” is unchecked, if checked click check box to uncheck this option > click apply > click OK.
