Firefox keeps changing Windows 10 scaling.
I have Windows 10 scaling set at 140%. This morning when I started Firefox, the scaling jumped to 175. If I change it back to 140% in Windows 10, it changes to 175% as soon as I start Firefox.
Is there a way to stop this?

Wow, I don't understand why that would happen.
Firefox 103 now applies the Windows "Make text bigger" setting as a zoom multiplier (Release Notes). But I'm puzzled why that would change the value.
You can set Firefox 103 to use 100% instead of looking at "Make text bigger". Maybe this will help?? Here's how:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.
More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.
(2) In the search box in the page, type or paste ui.textScaleFactor and pause while the list is filtered.
Normally, Firefox will display a bar with Boolean Number String and a plus button. If Firefox displays a row that already has a number value, skip to step 5.
(3) Click the circular button in front of Number and then click the + button to create a new preference. (See composite screenshot below.)
(4) Firefox should display an editing field, and show a value of 0 -- edit the value to 100 then press Enter or click the blue check mark button to save the change.
(5) If the current value of ui.textScaleFactor is NOT 100, then double-click the preference to display an editing field, and change the value to 100 then press Enter or click the blue check mark button to save the change.
