Using Firefox 8.0 on a MacBook Pro I can no longer enlarge the text on web pages by sliding apart two fingers. Why?

I just downloaded Firefox 8.0.1. I have a MacBook Pro running Mac OS X 10.5.8. In the past, I could easily enlarge text on a web page by sliding two fingers apart, or likewise, make the text smaller by pinching the fingers together. I can no longer do this with the latest version of Firefox. If I run Safari instead, I can still use this feature of the Mac. Is there a setting I need to change? Or is it a glitch in the new version of Firefox?

Some gestures have been removed in Firefox 4+ versions.

You can restore the zoom feature by changing the values of the related prefs on the about:config page.

  • browser.gesture.pinch.in -> cmd_fullZoomReduce
  • browser.gesture.pinch.in.shift -> cmd_fullZoomReset
  • browser.gesture.pinch.out -> cmd_fullZoomEnlarge
  • browser.gesture.pinch.out.shift -> cmd_fullZoomReset
  • browser.gesture.pinch.latched -> false

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

  • Use the Filter bar at to top of the about:config page to locate a preference more easily.
  • Preferences that have been modified show as bold (user set).
  • Preferences can be reset to the default via the right-click context menu if they are user set
  • Preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean)
