What about those who would like to use Chromium on their desktops and Firefox on Android? Would it not be simpler to just translate the History file to places.sqlite, and rsync places.sqlite and cookies.txt to the handheld? With paired Bluetooth devices, that could happen every time the devices are in range.
If only browsers could standardize on formats for these things. If I were an Android user I'd probably extend Chromium myself (if I could figure out how to build it, that is ;).
