SeaMonkey 2.0 Alpha 3 contains the following major changes relative to SeaMonkey 2.0 Alpha 2:

• History is now stored in a better database solution, so that it can easily keep more information, and the location bar determines which addresses to autocomplete and/or show in the drop down menu with a smarter algorithm based on what you type, searching in both URL and title of visited pages by default.
• Password Manager was switched to an improved version, allowing easier searching, and notification bars replacing modal dialogs for remembering logins.
• Toolbars in the browser component are now fully customizable.
• Session restore (crash recovery) has been added. Now, when SeaMonkey crashes, all your browser windows and tabs will be restored automatically or on request (including data entered in web forms!). In addition, users can select to always restore the browser windows and tabs from their last open session when starting SeaMonkey.

See the SeaMonkey Trunk Tracker blog for more details about the changes between those pre-releases.
The changes page lists an overview of new features and fixes relative to our last stable release, SeaMonkey 1.1.14.

The SeaMonkey project provides official versions of SeaMonkey 2.0 Alpha 3 for Windows, Linux, and Mac OS X in US English and experimental language packs for a small variety of other languages. Community volunteers are also contributing builds for other platforms. You can download SeaMonkey 2.0 Alpha 3 here.

Before installing, make sure your computer meets the system requirements. SeaMonkey 2.0 Alpha 3 will offer to migrate your data from SeaMonkey 1.x or Mozilla 1.x at the first start after installation. You can find more details about installation, profile data and uninstallation in our install and uninstall document.

Extensions installed under SeaMonkey 1.x are not migrated to SeaMonkey 2, and may not be compatible for reinstalling in this version due to major changes in our architecture. Please report any issues to the maintainer of the extension. Extensions and Themes for SeaMonkey 2.0 Alpha 3 can be installed from the SeaMonkey Add-Ons website or the "Get Add-Ons" section in the Add-Ons manager.

This list covers some of the known problems with SeaMonkey 2.0 Alpha 3. Please read this before reporting any new bugs.

• MailNews account password prompts are no longer serial at startup (Bug 338549)
• IMAP accounts with over 1000 folders get error popups with message synchronisation switched on (Bug 462539))
• Profile Roaming is not working any more (Bug 378647)
• Download Manager doesn't support localization and has other slight issues - will be fixed by switching it to the Toolkit backend (Bug 381157)
• In some scenarios, multiple master password dialogs appear at once (Bug 381269)

• Poorly designed or incompatible extensions can cause problems with SeaMonkey, including make it crash, slow down page display, etc. If you encounter strange problems relating to parts of SeaMonkey no longer working, the browser not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble. Restart SeaMonkey in Safe Mode. On Windows, start using the "Safe Mode" shortcut created in your Start menu or by running seamonkey.exe -safe-mode. On Linux, start with ./seamonkey -safe-mode and on Mac OS X, run:

  cd /Applications/SeaMonkey.app/Contents/MacOS/
./seamonkey-bin -safe-mode

  When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.
• If you uninstall an extension that is installed with your user profile (i.e. you installed it from a Web page) and then wish to install it for all user profiles using the -install-global-extension command line flag, you must restart SeaMonkey once to cleanse the profile extensions datasource of traces of that extension before installing with the switch. If you do not do this you may end up with a jammed entry in the Extensions list and will be unable to install the extension globally.
• If you encounter strange problems relating to bookmarks, downloads, window placement, toolbars, history, or other settings, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running SeaMonkey with the -P command line argument, choose the "Manage Profiles" button and then choose "Create Profile...". Migrate your settings files (Bookmarks, Saved Passwords, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file.
