Every window and every task has a sidebar on the left. I can close it. But next time it will be there again. It runs Firefox Browser 80.0.1 Thank you for your help.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

the problem ist still there.

Can you post a screenshot of the whole page, please?

Thank you for your interest and help. I have around 15 Firefox windows open. I want it that way. When I turn off the PC, it is set so that all windows open again. It's set that way. Have a nice day.
