Firefox in Windows 10 left and bottom window gaps

I've had this problem ever since started using Windows 10.

I like to have the window flush to the top, left and bottom of the screen, when I close Firefox and re-open it there is a 5 or so pixel gap along the left and bottom edges, every time I move them back and re-open Firefox the gaps return.

It doesn't happen in any other program so it's not Windows 10 fault.

How can I fix this?

Try to rename (or delete) the xulstore.json file in the Firefox profile folder.

You can use this button to go to the current Firefox profile folder:

Thanks but it didn't work.

It does it from a fresh install before sync, it's something to do with Windows 10.
