I opened a page in Firefox and came back hours later. I reloaded the page (to see if something new was added), but had to notice that something got deleted instead.
Is there a way to see the previous version of the page? Does it get saved in the browser cache? Or will the cached version be removed as soon as I reload the page (and the content changes)?
(If I had expected a deletion, I would have opened the same page in a different tab instead of reloading the page in the same tab.)
