philikon / weaveclient-chromium. Hmm, a Mozilla Sync client as an extension for Chrome. Unfortunately, there is nowhere properly indicated how to install it and some comments on the net suggest that it probably does not run stably with newer versions. But maybe still take a look if I find some spare time. With this I could then, for example, connect Chrome on Mac or Linux with Firefox Mobile on Android. Since on Android the normal browser can't even sync with Google's own desktop browser (which is really embarrassing), this might be something.
