Bugzilla

Hi
I tried to replicate the issue using windows10 64bit and the latest Firefox release 71, but i don´t have the problem.
Perhaps one of the addons that you have installed is causing an issue. Do you have a full list of addons installed? 
Also i noticed you are using a dark theme, is that the default dark theme that you set on firefox hamburger menu > Customize?

Please download the latest Firefox Nightly release from here: https://nightly.mozilla.org/ and retest the problem.

If you still have the issue please create a new profile, you have 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

Lastly test if the issue is reproducible in safe mode, here is a link that can help you:
