I went and tried yesterday's official OSX build:
Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7a) Gecko/20040206 Firebird/0.8.0+
and find an old bug is back -- the 'login' button for spamcop.net does nothing.
(it's a script, used by several sites, has happened before with nightly builds)
and none of my stored passwords seem to have survived.
but some sites are still logging me in automatically.
So I'm going promptly back to your most recent OSX unofficial build.
----> Assuming I have to create a new profile (move my old one out,
run the new build so it creates a new profile folder) -- which
files can I safely copy back in from the saved old profile folder,
as an OSX user? I've gotten a LOT of answers to that question,
but never from someone who really understands the OSX build
files <-----
