Well, i first tried to go on a website to watch an anime, but it says that i need the flash player plugin installed which i don't for cause of lags. I tried installing the adobe flash player for firefox since i know that Internet Explorer and Google Chrome had it installed by default. So then, after installing it, something went wrong. The plugin seems to be there, but when looking at my active processes, it said that flash is running twice, which now make the videos on youtube and everywhere else start lagging seriously bad. I've tried searching for answers to that kind of problem, but i cannot seems to be finding one. I would need help please.
