First the stats...

Firefox: latest (64.0 (64-bit), just updated) MacBook Pro (Retina, 15-inch, Mid 2014) MacOS: 10.13.6

Issue... The issue is similar to questions, such as

https://support.mozilla.org/en-US/questions/1192723

When using multiple monitors with different resolutions, such as the laptop monitor and an external monitor of lower resolution, two things happen:

1) Windows that open in the lower resolution monitor, when maximized, do not have the background of the tab and url bar completely fill on the left hand side. As you grow the window, the background moves right, leaving white in the upper left.

2) When windows are opened from a window in the lower resolution monitor, but the new window opens in the higher resolution, the window is small and text is small, clearly not honoring the higher resolution window. Moving the window back to the low-res monitor then back to the high-res monitor resets the resolution.

I have tried the suggested Hamburgermenu -> Preferences -> Performance and disabling hardware acceleration. This makes no difference.

This sounds like a driver issue having monitors of different resolution can affect the driver and how it switches different resolution displays. Isn't there a setting in the driver to match resolutions?

Did you try to disable hardware acceleration in Firefox?

That is usually the first to try with display issues.

As stated, I had tried disabling the performance settings and starting in "safe mode": Neither affected the issues.

About driver settings: macos allows one to force resolution on displays. However, forcing multiple displays to work at the "lowest common resolution" is impractical just to handle a single mis-behaving application.

This is what happens when you use a lower resolution to a high resolution so unless both monitors can display compatible resolution what your asking it to do can't be done. Unless you have a dedicate GPU with multiple outputs this might fix the issue but if not then both monitors must have compatible resolutions.
