Tips - How to pin FirefoxPortable in windows 7

=== update ===
this trix has stopped working with v10 for some reason.
================

People have had problem to pin firefox portable in windows 7 so the right firefox profile starts and, at the same time, only get one single icon in the taskbar.

The problem have been:
1 - If you start firefoxportable.exe and then try to pin it, next time you start it you notice a new profile is started locally on the computer and not the profile you have used in firefoxportable. This is because firefox.exe is pinned.
2 - If you try to pin firefoxportable.exe instead from explorer, the right profile will start but instead you will have 2 icons, one for the pinned firefoxportable.exe and one new for firefox.exe thats starts from the firefoxportable.exe.

I had manage to got it to work for for both FF 7 and 8 but when I updated to 9 it stopped like it did from 7 to 8. But I didnt got it to work this time and didnt remember how I did it last so I search for a solution but didnt find any, just others with the same problem. But I knew it have worked for me before so I started to test different way to find out how I did it before.

This is how I manage to do it, for you that have had this problem too:

1 - Start FirefoxPortable.exe
2 - Right click on the firefox icon in the taskbar and pin it
3 - Close firefox, and open the properties for the pinned icon
(right click on the pinned icon. In the opened menu, right click on "Firefox",
Select "Properties" from the new menu.)
4 - Now change the Target so it dont point to firefox.exe but instead to firefoxportable.exe.
So it looks like "c:\...\FirefoxPortable\FirefoxPortable.exe"
5 - Change at the same time "Start in" from "c:\...\FirefoxPortable\App\Firefox" to just "c:\...\FirefoxPortable"
6 - Press ok and now it should work as aspected

Its very simple. But reed something that it wasnt possible because of different id´s for the two files. So I believe the way it still works is that, when it is pinned first, the "pin icon" itself is "tied" to the "id" of firefox.exe (which was pinned). But we could still change the target to another exe file, in this chase firefoxportable.exe without this to change. So we can start one exe file but when the second exe starts the "pin icon" see that exe file as "correct" and dont start a new icon. But because we still could start the portable version the profile loads as it should.

Have not tested, but this little simple trix, would probably work for other portable apps, like thunderbird, if they have the same problem.
