KeePass [http://keepass.info/] has worked well for me across Firefox and Android, though I haven't tried it on Chrome.

What do you mean when saying that KeePass works for Firefox?

It's likely GeorgeHahn means KeeFox - http://keefox.org/

"KeeFox connects Firefox to KeePass Password Safe"

That actually works rather well. You should add the toolbar button though, then it works like LastPass.
