I really wish they would get the update side of firefox sorted.
Amen to that one, David. Until I finally said the heck with it and fetched the 4.0.1 manually, the "check for updates" in 4.0 insisted I was right up to date.
And I sure wish they'd get the documentation, such as it is, in line with what actually happens with the new installation. According to the website info, all extensions you previously had are disabled until it can be confirmed they're compatible with the upgrade. But the ShowImage one (the only one I've bothered getting, so far) seemed to stay activated straight through -- but says it can't be checked for updates.
For all the cussing we do about M$, can you imagine how fast Gates and company would disappear if you had to totally uninstall and reinstall Win, IE, etc. each time there was an upgrade to those?
