I recently started downloading win32 talkback nightlies again now that
they've shrunk down to a more tolerable size. I've had a couple of
crashes, but talkback didn't kick in. Then I noticed a message in the
console log when mozilla starts up: talkback can't initialize.
I've just been unzipping the nightlies and starting up mozilla without
ever running -installer. Seems to me this worked just fine in the past,
but it's been a while, so I could be wrong. I'm just carrying over
profiles that are already migrated. Is it necessary to run -installer
with a new build, or is something else most likely the problem?
