Hi, It sounds like a setting was changed on your new tab page. These changes are usually caused by third-party toolbars or add-ons. I understand that you would like to know how to change it back. Not a problem, please follow the steps below: <!--Experiment 1--> # In the [[Location bar autocomplete|Location bar]], type '''about:config''' and press '''Enter'''. The "''This might void your warranty!''" warning page may appear. # Click '''I'll be careful, I promise!''' to continue to the about:config page. # Type '''browser.newtab.url''' in the search box to find it on the list. # Double-click on '''browser.newtab.url''' and type in ''about:home'' in the window that pops up. Restart Firefox and open a new tab to make sure the change was made. If there is any issues with plugins please also see: [[Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems]] Please post back with your results, we are happy to help.
