To whom it may concern, I have a new Amazon Fire HD 10 tablet that I installed Firefox Nightly for Developers on via the Aurora Store as Google Play services are not bundled with this device. I installed my usual add-ons of uBlock Origin, Dark Reader, and Bitwarden from the Add-ons page in the top right menu. Upon returning back to the new-tab page my screen inverted 180 degrees as I received a dialog prompting me to select a background. I was holding the device in what I believe to be upside down portrait mode, with the ports and buttons of the device facing downward and the wallpaper picker forced the screen into default orientation.

I'm not sure if this is the right place to report this.
