PROBLEM:
"Firefox used to have a screen full of my most visited sites open when I
opened a new tab. Now, after installing and uninstalling Incredibar
software (malware is more like it), I cannot seem to get the MyStart
page to stop opening when I create a new tab. Is there any way to
restore the original New Tab page that I had before?
"
SOLUTION
To manually reset the new tab page by entering about:config into the firefox location bar (confirm the info message in case it shows up), searching for the preference named browser.newtab.url and right-clicking & resetting it to its default value (about:newtab).
