Today I updated my Java to watch some videos in Firefox (which is the most recent version), but for some reason, now when I go to open a new tab, a stupid search engine site is the default page it opens to. I've tried the about:config method to change the browser.newtab.url name to about:blank, but whenever I click OK, Firefox doesn't save the changes and the search site remains the default. I've also tried putting in my homepage URL and about:startpage and nothing is working. I have also toggled with the browser.newtabpage.enabled to both true and false, with no luck.

Any other way to change this? Please Help!
