The release candidates include about 250 bug fixes since Firefox 1.0 PR
and we'd appreciate any feedback around any of those areas.
With this release, we're also featuring Mozilla Foundation builds for up
to two dozen locales (slowly trickling in. if you don't see your
language, try back in a bit.)
If you do find regressions from the Preview Release, please file bugs in
Bugzilla and nominate them as Firefox 1.0 blockers using the
"blocking-aviary1.0?" flag on the bug. Thanks for your help in testing
Firefox!"
