As Title,

Whenever I try to go full screen and hover to the top of the browser, It originally showed all my tabs, but recently it has not been doing that. When I hover over and over, the tabs maybe appear 10% of the time, but whenever I click somewhere else other than the Tab Bar, it disappears.

I think this bug happened ever since I enabled "Hide bookmark toolbar". I have since reverted it back, but the error is still the same. Weird, since my tabs disappear since it has nothing to do with bookmarks.

Chosen solution

Are you using code in userChrome.css that could be causing this?

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

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

I just had to do troubleshoot mode and refresh Firefox and it fixed it, thanks!
