Firefox does not open a new tab when you click the plus sign button which is actually a shortcut for opening a new tab. You have to open a new firefox window in order to get a new tab. Please help. Thanks.

I didn't have this problem before with Firefox. My kids must have pressed something or clicked on something that's the open new tab button does not function anymore. No matter how you click it, it doesn't open a new tab. Even if you click on file, then go to new tab, it still doesn't open a new tab. You have to open a new firefox window in order to do multiple browsing.

Hope you can help resolve this problem.
