Firefox 3: Full Page Zoom, and How To Get Rid Of It

Like many of you, Firefox 3 is my go-to browser for normal use, but v3 has one annoyance I helped someone fix today: they switched up the standard zoom (Ctrl + + or -) to enlarge everything, including pictures, and not just text. If you don’t like it, here’s how to put it back they way it was:

  1. In the address bar, type about:config.
  2. You will get a warning about changing things, read it and make the promise.
  3. You will see a loooong list of variables. To make things easier, type zoom on the Filter line.
  4. First item will most likely be browser.zoom.full, set to true. Double-clicking that will set it back to false. You can also undo the one that makes it remember the zoom based on specific sites, while you are at it.
  5. Close that tab and you are done. Your normal zoom is back.

There you have it. Curious about what other things can change? Check out this Lifehacker article. Or this one from GHacks. Of course, any change you make is at your own risk, but most changes are easy enough to put back the way they were.

You could just go to View | Zoom | Zoom Text Only, but by changing things this way, you get your feet wet with about:config, one of the things that sets FF apart from crappy IE6/7.
