Using the latest Firefox and Chrome on macOS.
I can refresh a page using ⌘+R. This doesn't reload any images if the browser thinks its cached version is still OK (even if it isn't).
I can also use Shift+⌘+R to force a refresh, this discards any cached images and reloads them as well. Except for the favicon, for some reason it keeps loading the favicon from its cache, even if I know it has been changed (on the server).
Is there a way to enforce Firefox or Chrome to absolutely reload everything for a particular page, including resources such as favicon.ico?
Of course I can delete my entire browser cache and history, or completely disable caching in the browser's settings altogether, but that's typically not what I want. I just want it to reload everything for that particular page, once.
