If your Firefox browser does not pass our compatibility check(nowe okno) due to session storage and you are already using the latest version, here’s how you can enable it.
You can enable it as follows (on Firefox) :
1. Go to your address bar, type “about:config”, hit enter
2. Click on ” I’ll be careful, I promise! “
3. Search for “dom.storage.enabled”, right click, hit “Toggle” to set the value to “true”
Et voila! Your session storage is now turned on.
