Tabs used to be on one continuous line with arrows on the side to scroll through them. Now tabs are grayed out in the background and not available. How can fix

已張貼

Sadly Firefox updated on Sept 5, 2018 and now the tabs are not in one line that I can scroll through. They are grayed out and hidden, not available. How can I go back to having the tabs in one line and the right and left scroll arrows? What is the point in having them unavailable in the background?

That is not standard behavior.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
