Hi frosty101, normally the new tab button is immediately to the right of the current tab. If you hover the mouse over that area and click, do you get a new tab -- or in other words, has the + symbol become invisible?

If a click there doesn't work, try restoring the default layout of the toolbar area. There's a "Restore defaults" button at the bottom of the Customize screen. More info here: Customize Firefox controls, buttons and toolbars.

Any improvement?

Another workaround: Ctrl+t

thanks for your reply no success i cannot see a + sign to the top right restore defaults also did not work it just removed my toolbars etc from the top i really want to see the plus sign to open a new tab and also have all the open tab available to simply click on to view

Hi, please try : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 62.0.0 with a Full Version Installer
