Firefox 4 Tab Problem

A couple of days ago the facility to open a blank Tab in Firefox 4 stopped working. This particular problem related to the new tab button. Whenever I click on the plus (+) symbol to open a new tab window, nothing seems to be happening. Clicking on File and then on the New Tab option doesn’t opens the new tab. Neither do the Ctrl + T works.

A Google for "Firefox 4 tab problem" suggested that the problem was caused by "Ask Toolbar" being incompatible with Firefox 4! I was not even aware I had the "Ask Toolbar" loaded! A forum thread offered the following solution:-

These are the steps to uninstall the Ask Toolbar from Windows XP, Windows Vista and Windows 7:-

For Windows XP:

• Make sure all the Web browsers or there processes are closed.
• Go to Start menu and Select “Control panel” and then select “Add/remove Programs”
• Search the Ask Toolbar from the list of programs installed (or the program with Ask logo)
• Click on Change/Remove to uninstall it.

Windows Vista:

• Always close all the instance of Web Browsers or related programs.
• Go to the following path Start > Control Panel.
• Under Programs icon select “uninstall a Program”
• Now Select the “Ask Toolbar” from the list and click on “Uninstall”

Windows 7:

• Go to the following path: Start > Control Panel > Programs > Uninstall a Program.
• Select the Ask Toolbar from the list of installed programs and right click to Uninstall.

I am pleased to report that the solution worked for me in Windows 7. I have to say when I first looked in the list of programmes I could not find Ask Toolbar. This is because it was listed as "Foxit PDF Creator Toolbar" but it was listed in the Publisher column under Ask.com.
