Browsers are designed according to the original Web paradigm of switching pages, and they're pretty much incompatible with anything more sophisticated. The "Back" button steps backward through each action you performed; that's fine if you're switching whole pages, but not so fine when you're switching parts of pages. For example, when you change sections inside Nexus, it switches two components: The header and the "arena", which contains the table of contents and messages. Clicking Back the first time moves the arena backward, but the header doesn't get moved backward until the second time you click Back.

You run into similar problems with Reload/Refresh--it restores the Nexus to its original state, not your most-recent state. And, as many have lamented, the address box never changes from its original address.

I'm inclined to make a Rule: Don't touch the browser controls--operate the Nexus through the controls provided.

I recently discovered that Mozilla will let me hide the button, address, and status bars. If I did that, would you consider it "high-handed" or "presumptuous"? People can be "funny" that way--even though those widgets contribute nothing when you're at the HabitableZone, and cause problems when used, a lot of people like the feeling of control and feel threatened when it's taken away, no matter how benignly. Or, those with a paranoid bent might feel that the site has "something to hide". Computers are relatively easy to deal with compared to people!
