Hi,

I have tested your issue on Release version 82.0.2, Beta 83.0b8 and latest Nightly 84.0a1 (2020-11-03) using Ubuntu 18.04 and Windows 10 but could not reproduce it.

If the issue is still reproducible on your end, can you please retest this using latest Nightly build (https://nightly.mozilla.org/) and report back the results? When doing this, please use a new clean Firefox profile (https://goo.gl/AWo6h8) to eliminate custom settings as a possible cause.

Thanks for the report.
