Go to your Mozilla tools menu and click on Addons. Then click the extensions tab. There's an extension called Searchbar 1.2 by zugo and it's the cause of the problem. I got it downloading some xvid crap to watch an episode of Hung online.

thanks so much . fixed the problem perfectly!

Click on the toolbar options icon - it a spanner which should be the bottom row of toolbars, second from right, next to the apps + icon. Then select additional options Then uncheck "show a search box in new browser tabs"

I had the exact same issue; I downloaded xvid (trying to watch entourage), and I got the issue with Bing. However, when looking through my extensions I did not have Searchbar 1.2. To fix the problem I simply disabled all my extensions until I found the culprit and then I removed it.

".... and then I removed it. "

Posting the name of that extension might help another user with that problem solve it a little quicker.

I have the same problem. I downloaded oovoo and I had a slew of problems that I have almost fully sorted out except for this. I checked my extensions, but only have a few items there that were there prior. However I did disabled them all and the problem still occurred. I have since re-enabled them. None of them are under the name given above. Can anyone give me any suggestions on what to do?

I had the same problem with Bing showing up when I opened a new tab. It was extremely irritating because the cursor was placed inside the search box and I had to click inside the address area to go to a site.

The culprit was this extension:

StartNow Toolbar 2.3.0

I have no idea what that is or where it came from but I am glad to be rid of it. Thank you for the posts which pointed me in the right direction for the solution.

I got rid of it by deleting the extension "StartNow bar" that stealthy installed itself without my consent.

I had the same problem but the cause was searchtoolbar loaded when I installed open office.

this worked for me! :) Thanks
