How to know if url is already bookmarked

Question

I am adding bookmark from code. Now in Firefox if user already added the url as bookmark he should not be able to bookmark it again. How can I do it? For now every time a new bookmark is getting created.

Answer 1

If you want to prevent people from clicking a bookmark link on your website for a second time, you could try to write using cookies to hide the link if there's a cookie on the client.

As far as I know trying to check the bookmarks library (Places) in FireFox by using javascript on your website, that is impossible.

Answer 2

Obviously, you cannot, except for the above two good suggestions: use cookies. Or user information (although if they registered, they probably already bookmarked the site!). Cookie solution is brittle, though, as user can erase them.

Why you cannot: that would be an obvious security breach if a JavaScript program could read the list of bookmarks of the user: beside privacy concerns, one can have some sensible information in the URL parameters...

Side note: adding a bookmark is done on user action (or should be!). So users should know if they added the bookmark already, no?

Answer 3

getBookmarkIdsForURI()

"This method retrieves the list of bookmark IDs that contain the given URI."

Answer 4

As an alternative, try setting a cookie whenever the user bookmarks your site using your Javascript. If the cookie exists, remove the bookmark button (or whatever).
