I think what I'd do is try to start over.
Click start programs
look for the Quicktime folder and click on uninstall
At this time I'd also think of uninstalling Firefox.
Click on start
click on remove Firefox.
and download the reg cleaner.
After you download the reg cleaner open it and look at the soft ware section
look for Apple computer and check the box for Quicktime.
Also look for the box Mozilla Firefox and check the box.
click on remove selected then exit the program.
Restart your computer.
Then go online and using Internet Explorer go to
and download Quicktime. (I hardly ever use Quicktime except for when I go to http://www.cedarpoint.com and/or http://www.HersheyPark.com go on the rides)
Install Quicktime and then restart your computer.
and download Mozilla Firefox.
Go to here and get any plugins that you need.
Here are a few extentions that I use
Adblock filterset.G updater
Hope this helps.
I am running XPpro-SP2 with Firefox as my primary browser. There are some websites that notify that they must have Quicktime to operate properly, but if I load it many other websites refuse to operate properly. Usually you get a big box with a Q and ?. Does anyone have a fix for this or do I have to choose between Firefox and IE. By the way all the websites worked fine a few weeks ago with Firefox, and still do with IE.
Thanks for any help
