Okay, so the other day I downloaded this one add-on to Firefox called "Swiffout" that lets you play flash games in complete fullscreen. Only thing is, it goes to it's web page every time you leave fullscreen, and that can get kind of annoying. I later downloaded this one add-on that maximizes the game, but not to full screen. If anyone has any good add-ons for fullscreen, just leave a comment below.
Having security and privacy add-ons are good if you want to be safe.
That isn't difficult to follow, master565. It's quite easy to get used to it after a few times of doing it.

Then add in the game name. If it has more than one word, then space each word with a - sign. Then, put another - sign and put the number of the game beside it. Finish with .swf
That makes the game come out in a larger screen.
I remember doing it my first time while playing Exit Path, then I did it to other games such as Vector Rush so that I could see the screen better. For small games it's great.
Add-ons on the official Mozilla site are safe and tested, although not always coded in an efficient manner. Still, I can't imagine browsing the web without my set of FF add-ons and extensions.
