the macbook preo allows you to enlarge what is on the screen by spreading two fingers away from each other on the touch pad. The new ,ozilla firfox does not allow this to happen! When I could use it and enlarge type or a page to see better.

Some gestures have been removed in Firefox 4.

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.

In some cases, Toggle will be the selection offered for boolean (true-false) preferences. To reset a preference to its default value or to remove an added preference, context-click (right-click) on the preference and select Reset. If you added the entry via about:config, the

When I double clicked on the above browser settings in about:config - a box came up and I pasted in the suggested settings. It did not work in Firefox 4. I reinstalled 3.6 and now pinch gesture isn't working in that either.

Am I setting the preferences correctly?

Can you attach a screenshot with that part of the about:config page?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).
