webapps doesn't show up

Ubuntu 12.10 comes with a new Unity webapps features that allows you to integrate your favorite websites with Ubuntu desktop.

These webapps are installed on your desktop like native apps, they can be pinned to launcher and can be used with messaging menu, sound menu, HUD etc.

I am now using Ubuntu 12.10 and my gmail account doesn't integrate into Unity webapps.

I have checked the configuration in firefox preferences and also in the dconf-editor and I found nothing wrong.

I also googled the problem with no result, so I'm quite lost right now. Any news of which I haven't heard?

I found in another question on AskUbuntu someone had demonstrated on how to enable/disable sites that would integrate with Unity, in the webapps preview. There was a screenshot showing a "Unity" section in the Firefox preferences. I don't have that option. This is the screenshot:

How can I get this option?

When I open Firefox and visit any of the webapp enabled webpages I have installed, I get a launcher icon for them. The same does not appear to be when I use for example Google Chrome. Do webapps only work for Firefox?

I removed the package apt-get remove unity-webapps-facebook. After restarting, nothing but my desktop icons show. The top menu, and the leftside one is gone.

Opening the terminal with Ctrl+Alt+T, and typing unity tells me It's been uninstalled.

I saw the webapps are now available via synaptic (unity-webapps-*) and gave them a try. Now I have uninstalled them but I can still see the webapps in the applications scope and in the messaging menu. Clicking them just opens a new chrome window (chrome is my default browser) but all the webapp functionality is gone.

So how do I remove the icons?

i tried to install unity-webapps-preview on the long term support version of ubuntu 12.04 64bit.

I used that HOWTO: http://www.webupd8.org/2012/07/install-new-ubuntu-webapps-technology.html

but everytime i try, that happens:

tom@Tom-Laptop:~/Downloads$ sudo apt-get install unity-webapps-preview Paketlisten werden gelesen...

So I was just trying out the Ubuntu 12.10 webapps feature, but they don't seem to be working as they should.. I notice a few things that (to me) don't work as intended, or shown of in some video's.

First of all, most of them don't integrate with the messaging menu, even if they should. For example, as far as I heard, the GMail webapp should show in the messaging menu, but it's not there at all.
