Chrome有一个Bug，就是一旦你不想存某个网站的保密后，下次你想存也没有的存了。

下面是恢复方法：

If you’re a Google Chrome user and you’ve ever hit “Never for this site” by accident (or have girlfriend who does so consistently), it’s a little tricky finding out how to edit these “Save Password” exceptions. It’s pretty clear for Windows’ Chrome:

A little snooping reveals that Chrome keeps its login information in a SQLite database file:

C:\Users\(User Name)\AppData\Local\Google\Chrome\User Data\Default\Login Data

To remove an entry from the exception list, do the following:

1. Shut down Chrome
2. Probably a good idea to make a backup of the database file
3. Open the database file in a SQLite database browser; I use SQLite Database Browser
4. Select the “Browse Data” tab
5. Sites for which “Never for this Site” has been selected will have the value 1 for the column blacklisted_by_user. Double-click the desired cell, change the value to 0, and click “Apply Changes”
6. Save and close the database file
7. Restart Chrome
