Does offline mean disconnecting from the internet or simply logging out of the account?
The latter. I open the forum from a bookmark, there's no history, and only the main forum page kept refreshing. I wrote above that it's fine now, it doesn't refresh.
I tried opening the main forum page in FireFox, then two sites, and then back and forth — everything opens quickly without additional reloads, the page is available in the browser history. If we're talking about a fully offline mode when the internet is disconnected, I haven't tested that.
Now I've figured out that this happens with a page from a bookmark. I saved the main site page to bookmarks, cleared the browser history and closed it, opened it, opened the main site bookmark, navigated to the forum, pressed Alt+Left, and the main site page refreshes, but with Alt+Right, the main forum page doesn't refresh. Damn browser, lol. I haven't noticed this on other sites yet, or maybe I just wasn't paying attention to the ones I constantly use from bookmarks.
