I tried the 'about:config' and is was just the same as clicking on zoom and changing from 100% to 110% or from 100% to 90%. That's not what the pinch gestures do in other browsers.

This Multi-touch Zoom plug in actually duplicated or replicated what I wanted. I just wanted the view or the browser interface to zoom without the content changing. THIS IS A PERFECT SOLUTION.

Thank you @haxiomic

Haxiomic advice works perfectly for Pinch and Zoom. Thanks for being a stand-up guy: Update:
Native smooth zoom is starting to appear in newer Firefox builds. Try enabling it by going to about:config in the url and setting apz.allow_zooming to true. If that works for you then you don't need to use this plugin :)

Works perfectly out of the box! Many thanks this is much appreciated

I love it! I just miss a little feature we have on Mac: double tap with two fingers to zoom to an area of a website. That would make this extension PERFECT if possible to implement :)
