I love the WebKit nightlies, but every so often my plugins stop working entirely (Flash, Quicktime, etc.), forcing me to trash my prefs file and relaunch. A minor hassle, yes, but I’m tired of setting my tabbed-browsing preferences for the eleventh time. Shiira is, in many respects, fantastic, but I can’t seem to find an add-on that’ll do find-as-you-type. This is a deal-breaker. Why does the OS X browser landscape have to be so frustrating?
