The sessionStorage object stores data for only one session (the data is deleted when the browser tab is closed). The data will not be deleted when the browser is closed, and will be available the next day, week, or year.

Regarding this, does sessionStorage clear on refresh?

On this Page The sessionStorage property accesses a session Storage object for the current origin. A page session lasts as long as the browser is open, and survives over page reloads and restores.

how do I clear localStorage when browser is closed? No, LocalStorage remains persistent until it is cleared. sessionStorage is deleted when the user ends the session by closing browser or tab. No, until the user removes it on all browsers. It is persistent meaning the stored data will still be there when you close and re-open the browser window.

In respect to this, how long does sessionStorage last?

It doesn't expire automatically. So if you never close your browser it never expires. So when the tab/window is closed the data is lost. Each sessionstorage area is allowed 5mb of storage (in some browsers 10mb).

Is session storage a tab?

Right, sessionStorage is not shared across tabs. The way I solved it is by using localStorage events. When a user opens a new tab, we first ask any other tab that is opened if he already have the sessionStorage for us. Click to “Set the sessionStorage” than open multiple tabs to see the sessionStorage is shared.
