How to restore bookmarks from Chrome?  I’ve seen a couple cases where either an update on chrome removed all previous bookmarks or user accidentally deleted all of them to migrate to another computer and since google chrome syncs, it removed all it from the user’s account instead of just locally.  (yes, some people get confused about the login for chrome and syncing, vs gmail so they just sign out of gmail, they think logging into gmail is the same as logging into chrome.[i guess i can see why, since the credentials are the same], but if you are one of these people, you can think of it as different sites allowing you to sign in with your facebook credentials, you’ve all seen that right?)

On the mac…

I have a Mac so for all you Mac users go to ‘user’ folder –>Library –>Application Support –> GoogleChrome –> Default and you’ll then see ‘bookmarks’ and ‘bookmark.bak’.  Copy the bookmark.bak to  bookmarks.  This will make the backup copy into the current copy.  Then restart your chrome, and the bookmarks should be restored.

On Windows XP…

On XP: Go to C:\Documents and Settings\<your_username>\Local Settings\Application Data\Google\Chrome\User Data\Default\on Vista: C:\Users\<your_username>\AppData\Local\Google\Chrome\User Data\Default\     Same as above steps, copy bookmark.bak to bookmarks.

On Windows 7…

1.  Go to    C:\Users\<YOUR USERNAME>\AppData\Local\Google\Chrome\User Data\Default

2.Once there, you should see a bunch of files. Two of which are called “Bookmarks”, and “Bookmarks.bak”. Copy the Bookmarks.bak file to a safe location ( I copied the “bookmarks.bak” file to my desktop).

3. Now, close Chrome. Rename the “Bookmarks.bak” file you just copied to “Bookmarks”, and copy it back in to that directory, overwriting the original one.
