If you had a Mac that feature is built into the OS :)
I was excited when I saw that Firefox on the PC had that feature of increasing fonts and picture sizes — but sadly I found that video didn’t change.
What you can do is manually set your video resolution in the Windows control panel to something lower when watching the game?
Yeah, I could. But it's also the case when I am browsing or watching other videos.

Oh, sure. Twist it a little. Sheesh!
That feature is NOT built into the OS.
What is built into OSX is a screen zoom feature. What raybbr is talking about is the quick change of the fonts in Firefox.
Yes, you can use the zoom feature to zoom in on a flash section of a page and view the video bigger, however if you want to see any of the text on the page, you will have to move the mouse around. The zoom feature works like a big magnifying glass, and trying to read with it makes my head hurt.
