When I first started using LastPass, it was lightweight, fast, and secure. Now it gets hacked regularly, it's become too slow, and there are constant bugs in both Firefox and Chrome. They have even changed the behavior, how you can manage the passwords. Before you could change the entries at any time without leaving the page, now you have to go to an external page to the Vault (the Vault page is very slow) and make the changes there. This is a clear step backwards. I think it's time to look for an alternative.
