I have a mv3 chrome extension in which I do not register chrome.runtime.onUpdateAvailable. I save some of my variables by chrome.storage.session.set to keep their values when service worker restarts. This works fine until my extension updates, all session storage is removed after update.

What I want to achieve is: either to preserve session storage across update, or make extension update happens only when browser restarts (in this case i dont need to save my variables any more).

What are extension updates? Does that mean reloading after modifying the files that make up the extension? – Norio Yamamoto Feb 28 '23 at 04:47
no, i mean update from web store – byq Feb 28 '23 at 05:56
Is this a problem when you update the version of the app you publish on the chrome web store? – Norio Yamamoto Feb 28 '23 at 06:08
yes, session storage data is lost when extension updates from web store – byq Feb 28 '23 at 06:34
Reloading the extension will initialize the session storage. I believe updating via the chrome web store is the same. Is there any reason why `chrome.storage.local` can't be used? – Norio Yamamoto Feb 28 '23 at 07:37
because i dont want to preserve these variables when browser restarts – byq Feb 28 '23 at 08:26
You can initialize it with `chrome.runtime.onStartup.addListener` when restarting the browser. – Norio Yamamoto Feb 28 '23 at 10:18
There's no solution other than [Persistent Service Worker in Chrome Extension](https://stackoverflow.com/a/66618269). – wOxxOm Feb 28 '23 at 10:48
