New releases of Mozilla, Firefox & Thunderbird...

From the Mozilla.org mailing list:

With last week release of Mozilla 1.7 RC1 (Release Candidate 1), the Mozilla Community is counting days for the upcoming release of Mozilla 1.7, Thunderbird 0.6 and, specially, Firefox 0.9 (code named One Tree Hill).

The expectation is bigger than usual for Firefox 0.9 since, according to the roadmap http://www.mozilla.org/projects/firefox/roadmap.html
it will be feature-complete. This means, that any feature Firefox 1.0 will have, will be already available by 0.9. Among other great improvements, a new Extension Manager/Updater should finally fill the gap between Firefox and its extensions, allowing users to browse for available extensions and keep them up to date.

For an early preview of this feature, check these screenshots by Ben Goodger (Firefox's main developer):

Other enhancements coming to Firefox by 0.9: changes to privacy options user interface, a new e-mail button to open the default e-mail application and a selection of bundled extensions (browsing enhancements) you may choose during setup, similar to this draft:
