hello there...the stock browser does not allow certain things to be downloaded especially if the file type is different then the os.
this is what happened to me.
so first of all enable the option to allow non store apps in settings.
then download the file to a pc and transfer it to the phone.
fennec nor opera supports flash...and both are buggy in my opinion..but u r free to try...opera has to be installed through x terminal after enabling developer mode...fennec can be install without much hastle....will find a link for it and post it here...
