So I recently rolled over to Gnome Classic and in doing so tried a few extensions. Now for reasons that aren't relevant I disabled all of the extensions that I played with and since I couldn't find a GUI method of uninstalling them.. I went into the dir:
~/.local/share/gnome-shell/extensions and deleted all the directories that I no longer wanted the extensions from.

Now what's weird is that every time I reboot after logging in I am prompted to install all those that I removed.  What config file must I edit to stop that from happening?
Thanks!
