[Wlug] Cross platform password management

Hey all, I'm looking to overhaul my password management, so I'm looking for suggestions on what apps people are using. My ideal system would have at least these features: - cross platform on windows, Linux, and android - synchronize via 3rd party cloud storage, preferably google drive - *not* via an app specific service - good Firefox plugin Any suggestions on what to try, or to avoid, would be greatly appreciated. Thanks all! -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
