Works fine on webdav so far.

The first sync after adding a second browser always seems to be a bit problematic. Second browser seems to want to delete existing bookmarks from the file but stops due to an in-built failsafe.

Following syncs appear to be fine but takes a few minutes before the second browser recognizes changes in the file, even when clicking sync button, not sure why.

I will keep using it, but will take plenty of backups.

A built-in backup function would be much appreciated, for example writing a series of backup files every time there is a change.

Another good feature would be a confirmation dialogue if changes happen asking if you want to delete or change X bookmarks in the existing file or on the server.
