As far as I understand, Alexey has an installer for a multi browser extension\add on. He wants the Uninstaller\Repair Installation\Reinstallation program to check or not check a check box when a certain edition of the extension (for example, the Chrome edition) is not installed (whether it was never installed in the first place, or manually uninstalled).
So, no, there is no way to do that, but there was a discussion about something like that. If you add an NPAPI plugin that will work in the background (there will be call to it in the background page, for example, assuming that works), will uninstalling the extension kill it immediately, or let it execute some kind of shutdown instructions? If so, perhaps that is the way to go. It would require some C++ knowledge\programming and messing around and an approval from the team when you upload to the gallery, but if that check box means a lot to you - I am sure you can handle it. ;) ☆PhistucK On Mon, Jan 4, 2010 at 01:43, Finnur Thorarinsson <fin...@chromium.org>wrote: > I think Alexey is asking for an event that gets triggered when the user > manually installs an extension that was installed by Alexey's installer.
