It sounds like your PC has some malware which has hijacked the new tab page. Watch out for other changes as well e.g. to your default search provider, start page etc.
If you know what software might be causing the problem you should uninstall it completely from your PC. Also check your Firefox Add-ons and remove any that you didn't install yourself. Disable or remove Add-ons
You can then try these free programs to scan for malware, which work with your existing antivirus software:
- Microsoft Safety Scanner
- MalwareBytes' Anti-Malware
- TDSSKiller - AntiRootkit Utility
- Hitman Pro
- ESET Online Scanner
Further information can be found in the Troubleshoot Firefox issues caused by malware article.
Once you have removed the software that caused the problem you may still need to reset the new tab page to its original setting. You can do this with the following steps:
- Open a new tab
- Type About:config and click enter
- Tell the pop-up that you promise to be careful
- In the about:config search type "newtab"
- Find the setting "browser.newtab.url"
- Right click on the setting and choose "Reset"
- Close the about:config page
Your new tab page should now be reset. Check it... (you may need to restart Firefox first).
It is very important that the malware that originally caused the problem is completely removed otherwise it may just make the change again.
I hope that helps.
