You may need to remove an Ask extension. You can check on the Add-ons page:

Tools menu > Add-ons

In the left column, click Extensions, then disable/remove unwanted (or unrecognized) extensions.

The actual address for the new tab page is a hidden setting. To adjust it:

(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 search box that appears above the list, 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 thumbnails (default) => about:newtab
• Blank tab => about:blank
• Built-in Firefox home page => about:home
• Any other page => full URL to the page

Press Command+t to open a new tab and verify that it worked. Fixed?
