@Cormaca18
chrome.storage.sync.set takes an Object as the first argument. You can probably add some more keys as you want.
chrome.storage.sync.set({
"data1": data1,
"data2": data2,
"data3": data3
}, function() {
...
});
Why is it that when I stored a new item the old one is removed?
Is there no way to retain the old entries?
@IzumiSy
Also, is there a way to perform CRUD operation using the chrome storage API?

It looks no way to do that without writing your own update logic like renaming the key of the value in updating with a new key-value pair.

No, there isn't. Chrome.storage.sync only provides simple set/get methods. If you want to do that, you need to write your own CRUD operation logics.
Thanks! I solved my problem
window.close(); this function had using method close to sync data? I have issues when user type in textarea and must sync without close popup.html of extension. Anyone has meet same issues? @IzumiSy
@iletai No, you don't have to put window.close(). That method is only for closing popup here, not for any finalizing.

@maskmanlucifer I have trouble using chrome.storage, but maybe your issue comes from the fact that you didn’t write "permissions": ['storage'] in the manifest.json file
Thank u <3
Thank you for this short & sweet example
