Die hard users of Chimera complained that Safari lacked the tabbed browsing feature that so enhanced their lives.
Wait no longer, my mac friends!
In beta 62 of Safari, which has yet to be posted for download, tabbed browsing can be activated via the hidden debug menu. Once turned on, pressing Command-T opens a new tab. In Safari, tabs are lined up in their own bar below the toolbar, much like the bookmarks bar. When the bookmarks bar is shown, the tabs are presented below it.
