If you are on GNU/Linux you can use built in tools with PGP (with a little help of bash scripts, and git if you want). I first saw it explained on this blog http://blog.sanctum.geek.nz/linux-crypto-passwords/ and has worked really well for me. Feels more robust and secure than browser password stores, though probably not as convenient but its up to you, convenience or security.
