Page refresh message shown on first visit

[WKFO]

In Firefox 110.0, the first time you enter CMF, it shows a page refresh message on the button, not a first time welcome message.

This is cumbersome.

As you can see, we store the variable refresh (bool) in the local storage to check if the page is refreshed or not. So it is set to true when the page gets unloaded. The problem is it always stays as true for the next visits of the landing page.

It is set to false after a "refresh" message is shown but I assume it is not working.

Any ideas @Cthulhu2?

1. Hm... It seems the sessionStorage does what you want.

if (sessionStorage.getItem("refresh") === "true") {
  sessionStorage.setItem("refresh", false);
  setRandomMsg(getRandomFromArray(REFRESH_MESSAGES));
}
...
window.onbeforeunload = function () {
  sessionStorage.setItem("refresh", true);
  return;
} 

2. Also there is the PerformanceNavigationTiming.type property with reload value in the Performance API. May be it is more standard way.

performance.getEntriesByType("navigation").forEach((entry) => {
  if (entry.type === "reload") {
    setRandomMsg(getRandomFromArray(REFRESH_MESSAGES));
  }
});

Oh yeah, using sessionStorage definitely makes sense. I haven't heard about using the 2nd option.

Do you mind going ahead and creating a PR or should I do it?

Me neither. And there are not so many usages. We'll use sessionStorage.
