That is a disk image file and you can't open that in an application.
Make sure that Firefox gets installed properly.
Open the Firefox disk image (DMG) file with a double-click if necessary and drag the Firefox program to the application folder on your hard drive.
You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.
