Why can't I zoom in on text with my track-pad like I can with other browsers? I have a MacBook Pro. I used to be able to pinch and expand pages but now I can't.

Why can't I zoom in on text with my track-pad like I can with other browsers? I have a MacBook Pro. I used to be able to pinch and expand pages but now I can't. I have bad eye-sight and really enjoy and NEED this feature to be able to read most sites.

Hi dwightfontenot-

Some gestures have been removed in Firefox 4 and later.

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 or changed via the right-click context menu.
