I use multiple browsers and hence use LastPass.
LastPass in Chrome provides me with "Copy Username", "Copy Password" & "Copy URL" options from search results.
LastPass in Firefox does not.
On many websites I frequent I use multiple accounts and thus I need to use this feature. But as it is not available in Firefox, I am forced to go into Edit view of the site within LastPass and unhide the password and then copy it to use it.
Either LastPass should fix it or FireFox should provide some mechanism to import LastPass Passwords into FireFox's internal Password Manager.
