When I download the installation file of let's say Flash Player, it downloads it correctly. When I then, in the small downloads window, click the Flash Player download file, it, instead of installing, starts opening endless files (supposedly about 3000 per minute). I really don't know what to do.. PS: I'm on mac

You get that problem if you select the Firefox program to handle a file if you get an "open with" dialog.

You may have to delete the mimeTypes.rdf file in the Firefox Profile Folder to reset all file actions.

You can use this button to go to the Firefox profile folder:
