disable extension autoupdates?

[Admini]

I finally solved the problem by converting all my extensions to unpacked,
I can finally have control on whether an extension is updated!
chrome extensions updating system sucks in my opinion because of the above!
as I said before I come from firefox where controlling things such as that was inherent

You don't need to do that.
Editing manifest.json and deleting "update_url" is enough.
