Better tabs management in Safari 6.x I'm looking for extensions to allow the Safari 6.x versions to manage a large number of open tabs better than the current implementation. In particular I'm looking for two features:


Vertical tabs. This is possible in Firefox by means of the extension Tree Style Tab.
App tabs. In Firefox it is possible to pin tabs as app tabs.


Up to know I've found and tried several times SafariStand but it doesn't look great and it doesn't provide the features of Tree Style Tab. I would really like to move from Firefox to Safari, but for the problem of "I have too many useful extensions in Firefox." :)

Has anyone discovered extensions that add these features to Safari for OS X?
Safari does not allow extensions or plugins to mess with the tab bar. If you really need this functionality, your best bet is to use Firefox with the plugin you mentioned.
