I think there is no way to initially get a permanent ID of some sort currently, you will have to change it every time (if it changes, I am not sure it does) and change it after you upload for the first time (alternatively, your can create a localStorage value that will only be set on the unpacked extension, searching for that value will tell the extension to use the local ID and not the official ID, for development purposes). This sounds like somewhat of a mess and you probably should file a bug regarding this situation at crbug.com.
I believe it could take a few milliseconds, but probably nothing more than that (since it works over the RAM and not over the hard disk drive). You could test it yourself. I think there is simply no response and nothing happens, try it yourself. ☆PhistucK On Fri, Jan 1, 2010 at 11:37, Erek Speed <[email protected]> wrote: > I have a situation where I have a main extension which computes > results based on various data sets.
