Cannot open/close tabs that are part of an open folder - like ghosts

When I open a new tab, sometimes 2 or more tabs appear & cannot be closed and then that page is not able to be visited. They are like ghosts - they appear but you can't open/close them (they can be pinned, however, but still not able to be viewed). Thanks

Chosen solution

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

Thank you, cor-el! I think it's the Adblock Plus Pop-up Addon extension that caused the problem. I will post again if it starts again.
