I use (and like) LastPass under Android, Mac OS, and Windows, but I do not know its Linux status; You'd have to check. In Android, I tend to turn off all of its integration and use it manually, but that may be because I use Opera for my browser and it integrates a bit poorly with Opera on Android. I do not know if it does better with Chrome / "Browser" / whatever. But there is a client and you can either use it manually or have it integrate with your browser, and the client itself can also be used as a browser.
