Norton Safe Search took over my New Tab page in Firefox

I installed the Norton Identity Safe toolbar.  I also got Norton Safe Search.  I don't mind it checking my searches online BUT I do mind that it took over my New Tab page in Firefox.  Now whenever I click on New Tab instead of getting a tab with all of my tiles with my most used websites I just get a tab with Norton Safe Search.  How do I get my tabs back WITHOUT having to completely reset Firefox and lose all my other settings?
