<p>This is what puzzles me most - and I am hoping that jscher2000 will know what's causing it ..... (the window behavior, that is)

</p><p>Starting by opening FF (it remembers a bigger window than I had set) if I click the Maximize button the window grows even more. Now that I have seen this behavior, I believe the window size I set is trying to grow to the maximize window size each time I open FF.

<p>What difference do you notice between stretching the window to use the whole space and using the maximize button?
</p><p>On Firefox 68, if I stretch the window to fill the whole space while keeping it a resizable window (not maximizing), then exit out of Firefox, at the next startup, the window size is retained but there is a 5 pixel offset on the left side, like space is being left for an invisible window border. This might be a Windows 10 thing.

<p>Why is it dangerous??
</p><p>The privacy.resistFingerprinting preference is designed to fake out websites with inconsistent or false information, including window dimensions, to make your Firefox less recognizable as the guy from yesterday and last week. I guess that's why Firefox doesn't size windows the way it normally does and you may see more random sizing. I personally consider everything related to this resistFingerprinting preference to be experimental and potentially unhelpful, but it is still under development so hopefully it will improve in the future.
</p><p>By the way, do you prefer a particular window size/shape or do you generally maximize the Firefox window?

</p><p>I opened about:config and found the setting already set to false. Just for grins I changed it to true and restarted FF. The window was small. I stretched it and shutdown and restarted FF but it opened with the same small size. Switched setting to false and back where I started.

<p>Good luck with editing that. I suspect that Firefox won't hold your setting; IOW, Firefox will resume using the last setting as when Firefox was closed.
</p><p>Going back a few years to Firefox 28 &amp; earlier, there was an extension (Custom Geometry) that allowed the user to set the window size and position for launch, and it provided a toolbar button to manually set the user's defaults at will. That extension died when Australis was released in April 2014; I was able to 'hack' that extension to keep it working <em>(but with a few lost features)</em> to keep it working thru the run of Australis or at least theu the Firefox 47 version. IMO, am API needed to make such an extension work in Quantum isn't available. <em>One reason among the many that has kept me from using a Quantum version ... </em>

That information is stored in the <strong>xulstore.json</strong> file which is located in your Firefox Profile folder. It seems that with Fx 65.0 we have seen an increase is issues that are related to that file, but most user complaints are with the positioning of WebExtension icons not being remembered from one session to the next. <em>Personally, I haven't seen a xulstore.json problem myself with 2 different Profiles that I have for Fx 65.0.2&nbsp;; one that is very modified with extensions and other modifications, and the other which is basically a default Profile.
</em>
</p><p>You could try deleting the <strong>xulstore.json</strong> file when Firefox is closed, and then see if that window position issue is resolved the second time that you launch Firefox.
</p><p>You can open your Profile folder via the Help &gt; Troubleshooting Information. Scroll down to Profile folder and use the <strong>Open Folder</strong> button. Then close Firefox while the Profile folder is open in the Windows Explorer window, then delete that <strong>xulstore.json</strong> file, which will be at the bottom of the list of files in that Explorer window.
