SyncPlaces is a Firefox extension that allows you to synchronise your bookmarks
SyncPlaces is a Firefox extension that allows you to synchronise your bookmarks and passwords Between different installations of Firefox (e.g. a browser at Home and another at Work), and also to sort your bookmarks. It only works with Firefox v3 and above (but is compatible with older bookmark extensions). The synchronize feature requires your own Web or FTP server, which is used to store the bookmarks centrally, but there are a number of free servers you can safely use (see the Support section for Details of at least one of these).
Using your own server means you get to keep you bookmarks private rather than storing them on a third party server who may analyse, Probe and profile you, sell that data to others, or use it for their own nefarious purposes ;)
If you just wish to sort your bookmarks then you probably just want the SortPlaces extension instead.
If also takes a backup of your current bookmarks before overwriting them with what is on the shared server. So you can restore this backup if it all goes wrong and you can also manually take your own backup at any time.
Bookmarks are typically stored in JSON format as this is ideal for the storage of all the bookmark information from the new Firefox Places system (e.g. tags, queries, and annotations). You can also export/import or send/receive your bookmarks in XBEL format. XBEL is great for sharing bookmarks with other browsers or older versions of Firefox, or transforming with XSL to style your bookmarks so you can access them from any browser without installing the SyncPlaces extension. You can also send bookmarks in HTML format if you don't wish to style XBEL yourself.
Both passwords and the list of password exceptions are synchronised, and are automatically encrypted before sending to maintain privacy.
Other options available include file compression for fast transfers, encryption, auto-send and receive at regular intervals, and/or a set time, and/or at Firefox startup/shutdown.
