Comment 40 for bug 1033226

I'd be fine with a 'restart later' button or a 'don't remind me again' button, though I still think it comes across as arrogant to imply an immediate restart should be done without giving the user any specific details about which update(s) require a restart or why a restart is necessary.

I still think an informational dialog box with a single OK button would be the simplest way to get the point across, and I don't particularly see the need for a restart button at all when the user already has another convenient way to restart.
