Quick Auto Refresh by snyangqi.com is a Google Chrome extension that has a description of "Quick Auto Refresh is the best extension to auto reload a website ... click on the Refresh Firefox button.

The latest Windows 11 Canary build contains an early implementation of a Wi-Fi refresh button. Microsoft confirmed that it is working on it, but the current implementation is still raw.

A cache-overriding reload isn't a fix-all, but it is the first thing I tell anyone to try ("Hold Shift and click the Refresh button") when they're having a problem with a web site.
