Firefox browser window resets...
After reinstalling Windows 11 Pro on a newly installed SSD my browser resets location and size to default. Nothing listed here in support or found elsewhere through a web search has made a difference. Also, if I leave Firefox open for an extended period of time so that the browser stays where I put it, and keeps the same size, it will crash. As a test, I had Windows resize the browser to the full monitor, closed it, and when I reopened Firefox it filled the monitor. A second time closed and reopened a few minutes later resets back to default location and size. Everything else (bookmarks, extensions, etc.) remains the same. Nothing has been added or removed since the fresh install.
This is the latest version, 23H2, of Windows 11 Pro, which, btw, was the version I was running before the fresh install of Windows 11 Pro.
How can this be corrected?
