Constantly freezes up or refuses to work properly, forcing me to uninstall and reinstall it. I love LastPass, and gladly pay for the Premium features, but their Firefox implementation is shamefully buggy.

CONFUSING, FEEL LIKE I SIGNED IN 3 TIMES???

Last Pass makes me feel a lot safer on the internet. I have SO MANY passwords that the crooks will find me a waste of time.

Doesn't work well in Firefox - the buttons in the toolbar menu for fill/copy/edit just flat don't work. Also LastPass doesn't allow you to modify the associations between login credentials and websites. This is frustrating because on some websites/apps it suggests the wrong credentials and doesn't allow me to manually choose the correct credentials.
