Hi Amin,
instead of using a boolean preference just write your extension's version
string into the preference. Then on each program start you compare the
preference's string to your current extensions version to find out about an
update.
In my extension (checkyesss) I use it to trigger various stuff, but mainly
showing all new features (and bug fixes, d'oh) added between the old version
and the newly installed one when the updated extension runs for the first time.

Have a default preference, say "extensions.myapp.firstrun", and set it
to true.
Check it every time at startup. If true, execute the code, and if false
do not. Once your code is executed, you can set it to false yourself to
ensure the code is not run on subsequent startup.
