Xmarks (formerly Foxmarks) extension for Dolphin Browser.
Included as part of your Xmarks Premium account. There is a free two week trial available to all users.
Allows you to utilize Dolphin Browser instead of or in addition to the Xmarks app for Android. Use the Toolbar icon under 'Menu' in Dolphin to see it!
When you swipe or go to Menu -> Bookmarks, Dolphin Browser shows you your bookmarks toolbar. Be sure to tap Bookmarks at the bottom to see all your folders.
If all your bookmarks appear as one long list, go to Menu -> List view to view them in folders instead.
Sub-folders aren't synchronized to Dolphin Browser, but you can access them by tapping the Xmarks icon and selecting All Bookmarks.
