Pot Farm + Firefox = Fail

Yeah, I'm addicted to this Facebook game called Pot Farm...and I just recently discovered why my laptop and computer cant handle the game. I only have 1GB of RAM. Since Flash player and Firefox eat up so much memory, I now have to save up to buy a new laptop. I wish I knew this information before I purchased this shitty Hp Mini for $300. FML 

Here is a video of what I have to deal with.
