Safari has been very intrusive this time around, not only asking to be the default browser numerous times, but it also requested to import all my Firefox history and favorites.
Thing is, this version of Safari is really nice, and with the iCloud syncing with my iOS devices I've really been tempted to ditch Firefox. But without proper RSS support, it's a nonstarter. RSS is how I do all my news browsing. In Firefox I have feeds organized by category, and can quickly skim a site's feed to see if anything interests me. The latest Safari brought back RSS with its Shared Links feature, but that simply dumps every story from every RSS feed you've subscribed to into the sidepanel in a cluttered mess. No thanks.
