Currently our jump lists refresh at the following times: start, shutdown, and while running, every two minutes. Some users have requested that the running refresh time be moved to a pref. The value is currently hardcoded in the jsm - http://mxr.mozilla.org/mozilla-central/source/browser/components/wintaskbar/WindowsJumpLists.jsm#48 Move this to taskbar prefs and set the default to 2 minutes.

I switched to 30 seconds for better refresh as well.

Comment on attachment 446234 [details] [diff] [review] patch v.1 Is the rebuilding so cheap that doing it more often is a no-brainer? Was two minutes really a bad choice for the default behavior, i.e. are there concrete drawbacks for real world usage?

Over time people have complained about the delay, so now that we have a pref, I think it's safe to move it up to 30 seconds.
