Trackpad 2 finger pinch on Firefox

[Politis]

When I try the two finger pinch on my trackpad to enlarge or reduce an internet page, it does not do anything on Firefox pages. But it works with Safari and Chrome.
Is this a question of settings or a Firefox issue?

Thanks, I get this:

To enable pinch/zoom in Firefox:

Open a new tab.
Type in about:config and press Enter.
In the search pane, type pinch and press Enter.
Enter these values for the pinch.in and pinch.out prefs:

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


HOWEVER, I cannot type anywhere anything. Any ideas?

Type "about:config" into the field where you would normally type in the internet address.

Thanks, I already did that. I end up at the page you said but once there, I cannot type anyting. Not in 'preferencen name', not in 'status', not in 'type'.
Any suggestions?

OK, I found how to do it, you had to double click on each line
But now, it do the pinch and nothing happens :-(
