Save Last Session Of Chrome Extension

In my html file I have a simple table and a couple of buttons that allow adding/removing rows. If I store that html in popup.html, then every time I close chrome extension the sess

Solution 1:

You will have to use one of the storage APIs provided.

Best one to use is chrome.storage, but you can also use localStorage inside chrome extension pages. See this question for a comparison. You don't need background page for either.

Do note: you cannot store DOM nodes directly in such storage, since the data has to be JSON-serializable, and DOM nodes contain circular references.

So you'll need to store data used to add your rows instead of the rows themselves, and add them again when restoring state. It is a good idea anyway to store "raw" data.
