Bookmark Database Corrupted

If you see this error, it means that Firefox is reporting to Xmarks that the database files in which Firefox stores its bookmarks has become corrupted. This can be caused by improper shutdown of Firefox, or some other system problem. In general, Firefox (and Xmarks) will be unable to read from or write to the database in which Firefox stores your bookmarks until you take the action to resolve the situation.

We recommend that you set aside the damaged database files and allow Firefox to create a new database. You can then use Xmarks to download your latest bookmarks from the server.

1. Close Firefox completely. (Instructions on how to completely exit your Mozilla application, here.)
2. Open the Firefox profile folder. (Instructions on how to open a profile folder, here.)
3. Delete or rename all files named "places.sqlite", including "places.sqlite-journal" and any "places.sqlite.corrupt" files, if found.
4. Restart Firefox.
5. Immediately download your bookmarks from the Xmarks server:
   1. Click the Xmarks icon.
   2. Select, "Xmarks Settings".
   3. Go to the "Advanced" tab.
   4. Click, "Download Bookmarks".

Note: Xmarks only supports stable builds. If you're running a dev build, please install a stable build until that version has been released.
