Why does Firefox keep opening in a tiny window?
Firefox frequently - but not always - opens in a tiny window - which then has to be stretched to the full-window size it was until closed. Has started with this version: 91.0.2 (64-bit)
Thank you for your help.

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