In Firefox on desktop Mac: After a search, then clicking on a search result from the list of options, the selected link always opens as a half screen instead of the normal full screen I've always had in the past. I then have to manually spread the half screen result out to full screen. Clicking on any bookmarked link, they still all open normal full screen. Don't have the problem in Safari but I prefer using Firefox. This problem suddenly came up after many years of normal 'full screen' Firefox operation. How can I make these search results open as a (normal) full screen in Firefox - like they always used to do? Not very computer savvy if someone can give me 'Firefox for Dummies' assistance.
