Foxmarks: Error: Found Corrupt Bookmark Data
From Foxmarks Wiki
If you receive this message, it means that Foxmarks has detected a problem in the internal structure of your bookmarks that will prevent your bookmarks from being synced.
Automatic fix (easy)
The easiest way to fix this problem is to install the most recent version of Foxmarks (2.0.39 or newer), which automatically deals with this issue. Upgrade your Foxmarks version within Firefox by going to "Tools > Add ons" and clicking on "Find updates".

Manual fix
As an alternative, you can manually clean-up your bookmark structure by exporting and then re-importing your bookmarks as follows:
- Export your bookmarks. Open the Firefox bookmark manager by selecting Organize Bookmarks from the Firefox Bookmarks menu. Then select File / Export and choose a file to which you can export your bookmarks.
- Delete your current bookmarks. In the right-hand pane of the bookmark manager, select all your bookmarks (ctrl-a on Windows, cmd-a on Mac OSX) and de-select (Ctrl-click on Windows, cmd-click on Mac?) your "Bookmarks Toolbar" folder (this folder cannot be deleted while it is set as your toolbar folder). Click the delete icon in the top row of the bookmark manager to delete all of your bookmarks. Go into your "Bookmarks Toolbar" folder and delete all of the bookmarks inside in the same manner.
- Import your bookmarks. Select File / Import. If offered a choice, indicate that you want to import from a file. Select the file that you exported to in step 1 above.
- Fix your toolbar. Select your newly imported "Bookmarks Toolbar" folder in the right-hand pane. Then select Edit / Set as toolbar folder in the menu. Then, delete the old (now empty) "Bookmarks Toolbar" folder.
- Upload your fixed bookmarks. Open the Foxmarks Settings dialog (from the Firefox Tools menu, click Foxmarks / Settings...). On the Advanced page, click "Upload Now."
This process should repair the corruption in your bookmark file and allow you to sync properly.
