Just bought a laptop running windows 8. When I opened google using firefox, I clicked 'sure' when asked if I wanted to install the google search app on the start screen, then on the page that followed, when I clicked 'view app in windows store', I was asked to associate a program to open the link to the store, I naively, it seems, associated firefox.
However, this prompted a never-ending succession of tabs being constantly opened in firefox and I had to use taskmanager to shut it down.
I can't find any way of unassociating or disassociating to correct this issue, Anybody have any suggestions please?
I don't know if this will help but if you open Firefox with "about:blank" as the target you might be able to go to Tools -> Options. Then select the Applications tab. If you can figure out which item is causing the problem you can use the Action drop down box for that item to select Application Details. In that dialog there is a Remove button.
also try going to Start and right click on the google search app and uninstall it .
i just installed it the same way you di and was not asked anything about accociaon ,it just went from firefot to the app store and i hit install and no problem using it ,must be a problem with your Firefox as Reverentjim suggest
