What is your home page as it sounds like you are still using the old Firefox start page http://www.google.com/firefox hosted by Google that was used for Firefox 3.6.28 and earlier releases. It has not been maintained ever since Firefox 4.0 which has the default homepage of about:home since.

How to set the home page article link.

It started showing up on the last update. I had to reset my home page back to just google.com. Now everytime I open a new tab the google/firefox search page comes up with the error I mentioned. I want to go back to a blank page when I do a new tab. How do I get rid of this showing up on new tabs?

Do you have and Tab related extensions?

I didn't before last update. Who knows what's there now. I didn't ask for this google/firefox thing and would rather just have it gone. Do you know how to get rid of it? I did look in add-ons to see if something was added and didn't find anything related. Just flash stuff, and java.

Open a new window or tab. In the address bar, type About:Config. If a warning screen comes up, press the Be Careful button. This is where Firefox finds information it needs to run. At the top of the screen is a search bar. Enter browser.newtab.url and press enter. browser.newtab.url tells Firefox what to show when a new tab is opened. If you want, right click and select Modify. You can change the setting to;

about:home (Firefox default home page),
about:newtab (shows the sites most visited),
about:blank (a blank page),
or you can enter any web page you want.

The same instructions are used for the new window setting, listed as browser.startup.homepage.

There are two possible "gotchas" with the new tab page setting:

• If Firefox ignores the setting, one of your extensions may be overriding it. You can review, disable, and/or remove extensions on the add-ons page:
  
  orange Firefox button (or Tools menu) > Add-ons > in the left column click Extensions

• If the change works but at the next startup is back to the unwanted page, you might have a user.js file in your personal Firefox settings folder (your Firefox profile folder). This article describes how to track down and remove the file: How to fix preferences that won't save.

Thank you. This fixed the problem. It was a setting in the config.
