Here's what's new in this release of Firefox:

* Live Bookmarks

You can now subscribe to and read RSS feeds in your Bookmarks. When you visit a page that advertises a RSS feed by using a <link> tag, a RSS icon will appear in the status bar. Click it to view a list of feeds the page is offering. Click one to subscribe - this adds a Bookmark Folder that contains all the recent posts from the feed.
* Improved Find

Find is easier and more powerful now with our new Find toolbar. The Find toolbar (which shows at the bottom of the browser window) automatically highlights text in the page as you type and has a useful highlight feature.
* Managing Annoyances and Protecting Security

You can now open blocked popups, and the Extension install system now blocks all attempts to install software from sites other than update.mozilla.org. Users can add other sites to a list that allows them to offer software, but software is never automatically installed. In addition to these steps, several other measures have been taken to prevent phishing attacks and to highlight when a page is being viewed over a secure connection.
* Better Bookmarks

Numerous improvements to bookmarks including more reliable presentation of Site icons, and a split pane view in the Bookmarks window.
* Strong Encryption For Passwords Available

Passwords saved with the Password Manager can now be more easily encrypted with strong encryption by creating a "Master Password". If you create a Master Password, you are prompted once per session to enter the Master Password so that Password Manager can automatically fill in site logins. A useful feature for people who share computers with others and want improved security.
* Improved Compatibility for IE users

Undetectable document.all support for site compatibility and improved compatibility for keyboard accelerators further smooth the transition for IE users
* Better System Integration for GNOME users

You can now configure Firefox as your Default Browser on GNOME, and Firefox will adhere to your GNOME settings for edit field key bindings, etc.
* And a horde of other bug fixes...

Here are the highlights for this Thunderbird release:

* Global Inbox

POP3 users can now combine all of their POP3 accounts into a single global inbox under local folders.
* Comprehensive Data Migration

Switching to Thunderbird has never been easier since Thunderbird can now migrate all of your e-mail data including settings, mail folders and address book data from common mail applications such as the Mozilla 1.x Suite, Outlook Express, Outlook and Eudora.
* RSS Integration

Thunderbird now features a built in RSS reader which allows you to easily subscribe to and read news and weblogs that support RSS.
* Improved Privacy Controls

In order to help protect your privacy, Thunderbird now automatically blocks remote image requests in e-mails from senders you don't know.
* Improved Quick Search

Thunderbird now makes it even easier to manage your e-mail. Quick search now supports many different types of search criteria including the ability to search message body text. Thunderbird can also highlight the quick search terms in the message body.
* Other New Features

Support for using a master password to encrypt saved e-mail account passwords.

Linux GNOME users can now make Thunderbird their default e-mail client (Tools > Options > General).

If your network uses proxy authentication for HTTP, Thunderbird now correctly prompts for proxy authentication instead of silently failing.

Bug fixes too numerous to mention!
