I am not able to create a new tab, eventhough i have tried all ways to do it.
Normally the existing (current) tab has at the end an "+", and that gives you the option to make a new tab to the right. My Firefox tab does not have the "+", and I'm not able to create a new tab for another link. The new tab option is not working on my Mozilla internet browser.

Use Hotkey CTRL + T to Open a Blank Tab. Do the following too:
go to Help Menu -> select "Restart with Add-ons Disabled"
Firefox will close then it will open up with just basic Firefox. You can enable the Add-ons later. Check and tell if its working.
You can find the New Tab button showing as a '+' on the Tab bar.
You can open the Customize window and drag the New Tab button that shows as a plus sign (+) from the Tab bar on another toolbar and it will become a regular toolbar button like the New Tab button that you have in Firefox 3 versions.
If you can't find the New Tab button then click the "Restore Default Set" button in the Customize window.
Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout"
If you want the New Tab button at the far right end of the Tab bar then place a flexible space to the left of it.
