Hi,
I was unable to reproduce the issue, I tried on Firefox Nightly 79.0a1 (2020-06-22) (64-bit) and Release 77.0.1 (64-bit) versions.

Does this issue occur with a fresh profile as well? You can find the steps here: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

You can also try testing if the issue is reproducible in safe mode, here is a link that can help you:
https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

If after doing this you can still reproduce the bug, would you send a video of the bug?

Thanks in advance. I've already chosen a component for this bug in hope that someone with more expertise may look at it. We'll await their answer.

Regards,
Jerónimo.

Hi,

Sorry, I didn't react earlyer.

The problem disappeared with the updates installed a day later after reporting.

So the reported problem is gone.

I disabled all add-ons and checked if somebody else reported the assumed bug and then I decided to report myself, because this bug existing
more then 10 days was annoying.

I have been using firefox nightly for quite some years. I have seen many small annoyances, which most of the time disappeared within a limited amount of time, let's say a week.

Thanx

Willem
