The Mac version of FF has three Update options in addition to the manual Check for Update under "About Firefox":
-- Autmatically install (with further option involving add-ons)
-- "Check for updates, but let me choose whether to install them"
-- Never check for updates
The first one is flagged "recommended" and the last "not recommended" with further blahblah about "security" (um, is this a code word for google?). I have the middle option selected. That's how I learned that, to Firefox, "download" = "install". You can't simply download a dmg and then deal with it later.
Crystal ball suggests that Windows-Latin-1 is rearing its head somewhere in the background. Apparently browsers are not only permitted but ENCOURAGED to interpret 8859-1 (Vanilla Latin-1) as Windows-Latin-1, even though this includes 32 codepoints that are forbidden to Unicode-- hence the angry black diamond.

Nope, that wasn't it. The pounds sign is at a perfectly unimpeachable A3, so the worst that can happen is if utf-8 is reinterpreted as Latin-1, giving you Â £ (without space, because the Forums are too smart for their own good).
But wait! That is the problem. Reinterpreting in one direction would just give you an unwanted letter. Reinterpreting in the other direction means the browser has to deal with A3-- a codepoint that has no meaning in utf-8. It jumps straight from 7F (one byte) to C2\h\h (two bytes).
Incidentally, I make all my html UTF-8. Been doing it for years. The only entities you'll ever see are and —. (And, ahem, & > <. Those don't count.)
And the punch line is... In the previous post, I mistyped "font" for "language" and had to do a hasty edit. Two different things. Oops. The question arose because Firefox now thinks my language is iu rather than en. (Safari says iu-ca-- which is decidedly redundant, but explains why piwik only thinks I'm Canadian with Safari, not with Firefox.)
