I installed the prebuild for chrome and have been using it for the past day. I'm not certain, but it seems that lastpass isn't autofilling my credentials anymore unless the site is set to auto-login. What's more annoying is that for a site which isn't auto filled, this new version adds to the number of clicks required to fill in my logon info. In previous versions when I click the lastpass toolbar button, any saved credentials for the current site were listed on the bottom of the menu. I would click the credential set to use and click autofill. Now I click the toolbar button, then click "Show Matching Sites", then click on the credentials to use, and finally click autofill. It's only one more click, but it is quite annoying. I've got to believe that this is one of the most commonly used features of the toolbar button, to fill (or view, or edit, or take any action with) the credentials for the current site, what is the logic behind hiding it one level deeper in the menus?
