Waterfox extension displays incorrectly on secondary monitor on Windows 10.

[tcreek]

I have laptop with an external monitor connected.

Both screens are at resolution 1920 x 1080.

While the Waterfox extension appears fine on the laptop screen, once I move it to the larger secondary screen, it does not appear correctly.

I also have the same type of setup, but on Debian 9, and it displays just fine.

Here as it appears on the second external monitor
