Anybody know how to detect duplicate bookmarks in Firefox, Chrome? I try this Firefox add-ons (Bookmark Duplicate Detector 0.7.5) but its not support Firefox 4.0.1. Please help me?

With Opera you remove duplicates using Opera synch when you log into My opera servers & open bookmarks one of the options is you can search for duplicate bookmarks or folders and remove them.
Its done automatically but there is a warning the feature is still in beta & to backup your bookmarks first.

Maybe its done the same way in Chrome & Firefox ?

Thanks for help.
Do you know Opera sync server URL. Then i can directly connect Xmarks sync with Opera sync. And then i can remove duplicate bookmarks.

Well if Chrome or Firefox cannot do it when you synch them I suppose you could download Opera install it as a portable version by selecting options in the installer then change the install path to a different folder & install as a portable version
(standalone (USB)). Opera web browser | Faster & safer | Download the latest Internet browser free
Then you'd have to create a MyOpera account https://my.opera.com/community/signup/ and import your bookmarks into Opera then use Opera Link to Synch & go to your opera account online select bookmarks & remove the duplicates before exporting them.

All fairly straightforward probably take about 15 minutes
