Clearing cache in browsers
Sometimes when a lot of data changes on the web, or it has been a while since the site has been visited, clearing the cache of the browser will help load new data. Here is how to do that for several browsers. You should clear at least cached data, but do not have to clear passwords, visited sites, cookie, etc. if you do not want to.
The Firefox browser cache
The Chrome browser cache
The Edge browser cache
The Vivaldi browser cache
The Safari browser cache
Have not tested on a Mac, but this is how you should clear cache on it.
