I think if Firefox knows you're online, it will hit the server (sending e.g., If-Modified-Since), but if you go offline, it can tell and puts itself in offline

I think if Firefox knows you're online, it will hit the server (sending e.g., If-Modified-Since), but if you go offline, it can tell and puts itself in offline mode, where it browses from the cache only. You can do the same experiment just by doing File - Work Offline.
- ekiru 17y agoAh. Of course. I didn't consider that possibility. Now I've tried back/forward while connected to the internet and looking at Network Usage in Activity Monitor. I noticed that most of the times when I hit back/forward, there was no network traffic. I expect most of the traffic I did notice was either due to cache refreshes or due to other apps(probably mostly Thunderbird) I have running.
