How do I set new windows to be maximized by default in Firefox 42?

For instance, I get eBay emails with daily search results. When I click on them using my computer upstairs, they open a new window, as desired, maximized, as desired. When I use a newer computer downstairs, I get a new window as desired, but it is always some ridiculously small window that I then have to maximize.

I have tried right-clicking the Firefox shortcut and setting Maximized. Nothing. I have maximized manually, and then closed the window. Does not maximize the next new window. I am currently using the shift+click workaround, but it is irritating and unnecessary.

If there is a permanent way to fix this, please let me know.

My mistake... I tried this solution, and it seemed to work, so I went to click the "Mark It Solved" button, and the result was another minimized window!
