THANK YOU GGITech!!! Rated 5 out of 5 stars
The new Firefox 13 does stupid things when you open a new tab. I slimmed down how to fix it for those like me who don't like fussing around...
Go to about:config (Write it in the address bar.)
Paste browser.newtab.url in to the blank bar on that screen that allows you to filter through.
Click Modify and then delete out the value.
Now close it.
Yeah!! No more stupid weirdness just a blank page when you click new tab.
