How can I made the webpage fill my entire screen?

I recently had the hard-drive on my laptop reformatted and have had to reinstall my software. Firefox is my preferred browser and I am using the latest version. However, my bookmarked webpages no longer display the way they did before. The webpages no longer fill my entire screen, but have wide white margins on each side. I've looked through the Options in Tools but didn't find any setting that looked like it would fix this problem. Please help.

Hit F11 to toggle on and off.

Oops. I guess I didn't explain things very well. The problem isn't turning the full screen option on or off. The problem is that webpages that used to fill the entire screen from left to right -- horizontally -- now are centered in the middle of the screen with large bands of white space on the left and right sides of my screen.

Try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your add-ons is the culprit.

Reset the page zoom on pages that cause problems: View > Zoom > Reset (Ctrl+0 (zero); Cmd+0 on Mac)


You can use one of these extensions to set a default font size and page zoom on web pages:

NoSquint did the job. I'm pretty sure I had that add-on for the browser before the hard-drive was reformatted, but I completely forgot what was an add-on and what was part of the browser. It has taken a week to work through all those issues. In the meantime, I found a great new add-on called Read It Later, something I've needed for a long time!
