It doesn't work.

Klick an Zoom, sehr ergonomisch ... klein, fein und macht genau das was es soll.

Thanks for making this extension! It was great to have before Firefox made this native :)

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 :)

Great concept, something that needs to be implemented into the browser. However, it breaks YouTube playback in full screen after touching a touchscreen at all while on the webpage. Playback becomes a completely white screen. I disabled other extensions to ensure this extension is the cause.

Workaround: Go to about:config, search for "mousewheel.with_control.action" and set the value to 5 (this is for touchpad pinching and zooming, although it's a little slow). Set "apz.allow_zooming" to true for touchscreen pinch-to-zoom support. Revert any of the "browser.gesture.pinch" settings you may have changed for this extension.
