bookmarks.update()

bookmarks.update() updates the title and/or URL of a bookmark, or the name of a bookmark folder.

This is an asynchronous function that returns a Promise.

id

A string specifying the ID of the bookmark or bookmark folder to update.

changes

An object specifying the changes to apply, with some combination of the following fields. Any items not specified aren't changed in the referenced bookmark or folder:

title Optional

A string containing the new title of the bookmark, or the new name of the folder if id refers to a folder.

url Optional

A string providing a new URL for the bookmark.

A Promise that will be fulfilled with a single bookmarks.BookmarkTreeNode object, representing the updated bookmark. If the bookmark item corresponding to the id parameter can't be found, the promise is rejected.

This example renames all folders named "MDN" to "Mozilla Developer Network (MDN)".

function onFulfilled(bookmarkItem) {
  console.log(bookmarkItem.title);
}

function onRejected(error) {
  console.log(`An error: ${error}`);
}

function updateFolders(items) {
  for (item of items) {
    // only folders, so skip items with a `url`
    if (!item.url) {
      let updating = browser.bookmarks.update(item.id, {
        title: "Mozilla Developer Network (MDN)"
      });
      updating.then(onFulfilled, onRejected);
    }
  }
}

let searching = browser.bookmarks.search({ title: "MDN" });
searching.then(updateFolders, onRejected);
