I have created an XPI package. Signed it and deployed it on a web
site. Firefox downloads and installs the package. The only issue I
have is that FF asks me to restart FF after installation. I have
noticed that Adobe Flash plugin does not require restart of the
browser (although it seems it refreshes the page). Is there something
I can do to get the same behavior? My plugin has no UI. It offers some
processing functionality which is invoked from JavaScript.
