In the past couple of years, when I have synced my bookmarks, with Xmarks (Now using v44x) by overwriting the server bookmarks with my PC bookmarks, my PC Bookmarks Toolbar becomes a folder under the Bookmarks folder along with the other Bookmarks Menu folders.
In Firefox when I click on Show All Bookmarks the Main folder tree is
> Bookmarks Toolbar
> Bookmarks Menu
> Other Bookmarks
When I log into My Xmarks the tree is:
> All of the individual Bookmarks Menu folders and the Bookmarks Toolbar
This is not correct and when I sync from the server to my PC it sync with the Bookmarks Took =br as a sub-folder under Bookmarks Menu.
