Screen turns pixelated and crazy colors! WHY?!

Question

Hey, so I've had my MacBook Pro for a while and have never had any problems with it, but recently it's been doing this super weird thing.
When I'm on the internet (I use FireFox) and I go to a page that I need to input a username and password, I use an AddOn called Sxipper that remembers all my stuff for me. So when I'm on the page and Sxipper comes up with the list of my usernames and stuff, it used to just dim the rest of the page. Now, instead of dimming the page, it changes the colors to be all whacky and pixelated and I don't know why or how to fix it.
I've tried uninstalling Sxipper but it still happens on some sites, like sites that have changing ads on the sides (when the ads are changing, they change colors around super fast and then when they are ready to be the new ad the colors go back to normal). It also happens when I'm typing an address into the browser, All my stuff is up to date and I've tried running TechTool to see if there are any problems, but it says everything is fine.
Here are some pictures of what happens so you'll know what I'm talking about:

Hello,
FYI... <When I'm on the internet (I use FireFox) and I go to a page that I need to input a username and password> Why not allow Keychain which is in your Applications/Utilities folder do this for you instead of a 3rd party application...
Also, there's a utility on the net you can download to UNinstall software.. it's called:
AppZapper and available here: http://www.appzapper.com/
Next, get a good disk utility, several here to choose from:
If you don't use one, there are several disk utilities available to use.
Onyx, is free and available here: http://www.versiontracker.com/dyn/moreinfo/macosx/20070&vid=476445&mode=info
or
MacJanitor is good also: http://www.versiontracker.com/dyn/moreinfo/macosx/10491
or
and AppleJack here: http://www.versiontracker.com/dyn/moreinfo/macosx/19596
I suggest downloading from Version Tracker so you can view the Reviews/Customer Feedback and make a decision based on the information provided by users.
