Any other option besides a browser extension to refresh portlets? I have portlets set up with saved searches that I would like to have refresh every 5 minutes or so. Looking to do this via netsuite and not have to install an extension.

NetSuite support says that the dashboard portlets periodically refresh, but the portlets are designed so that people click the Refresh button on each portlet when they need the data.   Enhancement request 76300 for auto-refresh

A suitelet could be created to refresh data of a saved seach on the screen, but it gets rid of the portlets. Whatever is in the portlet would need to be made in the suitelet. Doable.

I’ve done this with a custom portlet script. The custom portlet has to be on the same page that you want to refresh. It will refresh all portlets on that page.
