LastPass is disappearing from Chrome when it updates to version 25?
Unfortunately Chrome's latest update (25) is disabling LastPass by default. There is currently no way to turn this off.
To get LastPass working again, you may be able to re-enable LastPass in your Chrome settings menu > Tools > Extensions.
If LastPass is not installed, please try reinstalling with our direct download link: https://download.lastpass.com/lpchrome_win.crx
If you see an error about downloading extensions, click the Chrome menu > Tools > Extensions and drag-and-drop the downloaded LastPass file to the Extensions page. LastPass should then be re-added to Chrome.
