Hi spbentsen,
do you mean the search engine bar next to the address bar?

Hi alco, no its when you open a new side, so that two pages are open on the same time. :)

Hi spbentsen,
so you try to open a new tab and the page shown is something else than google that it used to be? If this is the case:
check what Firefox has for the new tab page in the about:config preferences editor.

1 In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

2 In the filter box, type or paste newtab and pause while the list is filtered

3 Double-click the browser.newtab.url preference and enter the desired value:

• Page default

browser.newtab.url = about:newtab

• Blank tab

browser.newtab.url = about:blank

• Built-in Firefox home page

browser.newtab.url = about:home

• Any other page

browser.newtab.url = full URL to the page
Open a new tab and verify that it worked.
Please report back!

Try to reset some preferences to the default with the SearchReset extension:

• https://addons.mozilla.org/firefox/addon/searchreset/

Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
