tech help for samsung galaxy tablet

[tyrone girl]

Im back to be a pain in the ass again but this is driving me demented big time.
I know adobe flash player is no longer supported by android so after following diff steps on line I downloaded it. so its installed as an app but then its saying I have no plug ins. nos the instructions I followed are telling me to go in and enable plug ins on Firefox but ive spent all night trying to sort it. im absolutely thick when it comes to things like this as you have probably gathered but a few of u guys seem knowledgeable about these types things so someone please help if u can, I would greatly appreciate it.
