Store version variable in a localStorage and have local current_version variable hardcoded into javascript. Then during extension startup (in background.html) compare those two. After that update localStorage variable with the current version.

But now when a user first installs the extension, the version update popup will show too. How do you suggest I cope with that? – Orny Feb 06 '11 at 07:51

@Orny: Check if `version` exists? – Hello71 Feb 06 '11 at 15:58

I have submitted an answer and a working code example here chrome extension first run: Detect Chrome extension first run / update

You get the version from the manifest.json, you store that into your localStorage. In your background page, you check if your version has been set (via undefined) if it isn't set you know that your extension just installed, otherwise if the versions changed, you know it is being updating
