seit irgend einem der letzten Firefox updates funktioniert die zoom Funktion des touchpads des MACs nicht mehr, allerdings nur bei Seiten im Firefox browser!

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)

Thank you, that does the trick; the question arising, why did this have to be changed in the first place?

People used to change things by accident and those gestures were removed to prevent that.
