What's New in Mozilla 1.7 Alpha
This document outlines some of the new features implemented in Mozilla 1.7 Alpha,
important bugfixes and any new problems. See the "rough changelog"
for a more comprehensive list of fixes.
- Mozilla 1.7 Alpha includes several improvements to Mozilla's pop-up
- First, it is now possible to fine-tune it using two
preferences (dom.popup_maximum and dom.popup_allowed_events) but there's
no UI for that yet. Even without a UI, users should notice a greater
variety of pop-ups blocked (primarily mouseover pop-ups) and a limit of
20 or so open at one time, regardless of whether pop-up blocking is active
which provides some protection from sites that open hundreds of windows
in a loop.
- 1.7 Alpha also allows the user to review and retroactively
open blocked windows via context (right-click) menu on the statusbar
"blocked pop-up" icon.
- Downloaded files are now moved to the target directory as soon as the
user selects the desired location. This was the frequently reported bug
- There is now user interface to activate Smooth Scrolling (Preferences -> Appearance).
- This is the first Mozilla 1.x release with support for multiple
identities on the same mail account. See the
Multiple Identity Support
documentation for more details.
- 1.7 Alpha is also the first Mozilla 1.x release with support for relative
paths for mail folders in prefs.js. This makes it easier to copy profiles
around without having to fix up prefs.js afterwards.
- With Mozilla 1.7 Alpha, you can now edit address lists containing "Last,
First" style names.
- When composing mail, you can now use the up and down arrow keys to
scroll through the To/CC/Bcc list.
- On Mac OS X, attachment file names are no longer displayed in
decomposed Unicode but are converted to composed Unicode.
- All Mozilla LDAP queries now default to using LDAPv3 (previously,
they used LDAPv2). There is a hidden .protocolVersion preference
which can force LDAP v2 to be used on a per-server basis. LDAP
autoconfig authors can force v2 also by adding a setProtocolVersion
call to their JS. Details can be found by grovelling through
- Chatzilla has moved forward to version
which includes such improvements as:
- Support for the /ignore command.
- Font family and size can now be changed.
- Custom sounds are now working on Windows and Linux.
- Improvements to the user interface for half-op mode.
Under the Hood
- Mozilla 1.7 Alpha adds support for the onbeforeunload event.
This lets web application developers add code that alerts the user about
potential data-loss when closing a web application, or when leaving a HTML
page with potentially sensitive information.
- This release has a new SVG backend. The feature is not yet enabled in
the mozilla.org releases but developers may wish to compile with this
- Mozilla's binary size has been decreased almost 2% since Mozilla 1.6.
- 1.7 Alpha pageload times have been improved by 4% over 1.6.
- Mozilla 1.7 Alpha handles dynamic style changes much better (see bug
- Mozilla 1.7 Alpha has upgraded the NSS libraries to version 3.9.

These are items that have been added to the Known Issues page
since the last milestone, although the bugs themselves may have existed previously.
- Locale switching from the Mozilla Preferences window does not work in
1.7 Alpha. To switch locales, users will need to manually edit the chrome.rdf
file, replacing, for example, all en-US with de-AT, and US with AT in
