This is a tip you may already know about, because browsers have supported the feature for many years.
If you hold down the SHIFT key while refreshing a page (e.g. type CTRL-SHIFT-R or hold SHIFT when clicking the Refresh button in the tool-bar), it will tell the browser to ignore cached content when reloading the page.
This is a great way to resolve problems when something doesn't seem to have loaded correctly. Web site managers will frequently tell you to clear your cache to solve problems, but that's a pain in the neck. You need to dig through various screens in your browser's preferences in order to find the button to do this, and when you do, all web pages will need to reload everything, slowing down their load times until the cache gets re-populated.
Simply holding down SHIFT while reloading is much better. It's immediately available, so it won't distract you from what you were doing. And it only reloads the cached content used by that page.
This feature is known to be available with Firefox (source), Chrome (source) and Microsoft Edge (source).
On Apple Safari, use the OPTION key instead of SHIFT. (CMD-SHIFT-R opens the page in Reader view). (source).
I suspect most other browsers will also support this feature.
