I’m using Firefox on Mac OSX. At the end of the work day I log out of OSX, so Firefox and all of my other apps get closed.
When I log in again, Firefox opens automatically, and restores my previous tabs. This includes a tab for meta.discourse.org. In that tab I see my normal view, including my avatar in the top-right corner, but the content isn’t from the cache as far as I can tell, it’s obtained from the site.
Later (at least a few minutes), if I click refresh, the page that is displayed tells me that it’s not visible unless I log in. I log in again, and the normal Discourse home page appears, with pretty much the same content it had before (but updated of course, since it’s newer).
