I can repro on Windows:
1. Set OS display DPI scaling to 125%
2. Pick another app Foo that you can cause to open Firefox/links somehow. (e.g. by clicking a website link in its About dialog)
3. With Foo closed, right click on the exe, and edit its properties: Properties > Compatibility > Change high DPI settings > {both checkboxes ticked; override high DPI...: System|System (extended)}.
4. Open Foo
5. Cause Foo to open Firefox
6. Observe poor quality rendering in Firefox, and about:support shows the faked resolution and scaling=1.0 from the OS.
