When swapping my laptop between a station setup with 2 monitors and the laptop by itself, the resolution is changed and it looks awful.
I use a setup with an HP docking station connected to two monitors with my laptop closed. My current resolution is 1600x900 with 100% size, and firefox works just fine when I open it fresh on these monitors. But as soon as I un-dock my laptop and open it up, it's cut down to probably 1280x720, even though it still says 1600x900. The only way I've been able to fix it is to completely close out Firefox and re-open it, which is a real hindrance in my job.
Chrome works as normal, but Skype will look enlarged as well, but that is fixed by changing the resolution and back again (this does not fix Firefox).

Can you try with a more modern version of Firefox? Update to 61.0.2.
I wonder if this is an issue of your computer, not Firefox itself.

I have the most up-to-date version of Firefox ESR, 52.9.0
Firefox ESR 52 is no longer supported. Please update to the most recent version of ESR, 60
I upgraded to ESR 60 but I'm still having this issue. Also, now one of my TamperMonkey scripts isn't working :(
The resolution will change because each has different resolution and unless they are set to match or each monitory is set it is a Video driver and O/S issues that can't match output that would be a driver issue.
