As I say the tabs bar is open and you can see the desktop though it. There are no tabs there - clicking in the space does nothing. As I sought a fix for hours by disabling all add ons etc I did notice that when I opened "Customize Toolbar" that the tabs appear at the bottom of the page... I also noticed that if I click on a link a single tab appears down there and if I click a link in that page a new tab appears (the previous one disappears) and I can keep doing that. As I click the "X" on each to close it the one just before it reappears at the bottom of the page. I share all of this because it may offer clues. I, however, remain clueless. I hope I don't have to change browsers but I can't get anything done like this. Thank you for reading.
