Try clicking the PLUS sign next to the open tabs. If that doesn't work, right-click the navigation toolbar, select "Customize", locate the "New Tab" button in the resulting dialog, and drag it to a convenient location on your toolbar. Another way is to use the keyboard shortcut CTRL+T

With customize, I did drag the new tab button to the toolbar, but it doesn't work either. I tried all of your suggestions, but could not get a new tab to work.

The Ask Toolbar is causing the problem with being unable to open a new tab in the Firefox 3.6.13+ versions. Uninstall that extension.

There are a couple of places to check for the Ask toolbar:

• Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
• Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

I went to Control Panel as suggested, found Ask icon and text, uninstalled it and that solved the problem. So easy.

Thanks a lot the-edmeister.

I didn't have the plain Ask toolbar, as I have refused it whenever it was offered. However, I updated Foxit reader yesterday, and noticed it was included, but couldn't see any way to not install it with the upgrade. So when my New Tab button didn't work, and I read here that Ask was probably the problem, I went and found the Foxit Toolbar and got rid of it. That worked a treat, and my button works again. Using Firefox 3.6.18. Thank you Edmeister :) Cheers, Keith
