Commonly Requested Features

Application

1. UI "Skins"
   Mozilla uses XUL and Javascript to define its user interface. This makes it a lot easier to design and modify user interfaces. For example, you can add buttons to the user interfaces that do your own tasks. Different styles can be applied to the user interface using CSS files.

2. Cryptography in Mozilla
   Netscape can't release cryptographic source code to mozilla.org due to United States cryptographic controls. Neither can they implement cryptography APIs in Mozilla. However, Mozilla has a general plugin architecture, with which it will be possible to implement cryptography. See the crypto FAQ for more details.

3. Prevent Animations
   Mozilla currently has no support for this, but there is a bug report for it, as well as requests to be able to disable preferences like this on a URL-by-URL basis, and through a button in the UI that has a temporary effect (to turn animations on/off).

4. Standards Compliance
   The aim for the first release is full support for the W3C standards of HTML 4, XML 1, CSS 1 and DOM 1. There is some support for CSS 2, DOM 2, and XHTML, XSL, XLink and MathML, but whether any of these will make it into the first release of Mozilla is unknown.

5. PNG Alpha Support
   Mozilla currently does not support PNG alpha on all platforms, although hopefully it will before initial stable release. See the bug report for more information.

Browser

1. Automatic Form Filling, Password Saving
   Mozilla has a feature called "Wallet" that does this.

2. Embeddable Browser
   There are currently embedded versions of the Mozilla layout engine as an IE compatible ActiveX control, a GTK widget, and a Java widget. Questions should go to the embedding newsgroup.

3. Cookie Acceptance/Javascript Toggle Depending On Site
   Mozilla currently supports cookie acceptance on a site-by-site basis, and may do so for Javscript in the near future. Enhancement requests are filed for the Javascript issue and for applying this to a range of preferences.

4. "Go" Button
   There is considerable debate over the utility of a go button, and the debate continues. However, anyone will be able to design their own user interface for Mozilla, using XUL. And there is also an enhancement request to allow end users to customise which toolbar buttons they want.

5. Turn Off <Blink>
   There is currently no direct support for this in Mozilla, however, it is possible to do this with a user CSS stylesheet.

6. Preventing Popup Windows
   There is currently no support for this in Mozilla, but there is a bug report.

7. Advertisement Blockers
   There are various ways you can do this already, and it will probably possible to write a Mozilla plugin to do this. However, this proposal is very badly thought out as it will reduce the revenues that web sites get from advertising, which keep the majority of the web free of charge. Hence it is unlikely this will every appear in Mozilla or Communicator.

   This may eventually appear indirectly however, since things such as preventing popup windows and having preferences differ on a site-by-site basis can achieve this (these are above).

8. Page Errors Log
   There is currently no feature in Mozilla that allows the user to receive feedback and problems with web pages, such as bad HTML/CSS/DOM. There is a bug report discussing this issue.

9. ActiveX Support
   Mozilla currently has no ActiveX support, but it is possible to use a plugin as with Communicator 4.

Mail-News

1. Multiple Mail Accounts
   This is probably the most requested feature, and Mozilla supports this.

2. Filtering Existing Mail/Outgoing Mail
   Mozilla currently does not have this, but there are bug reports filed on outgoing mail, existing mail and a more general proposal.

3. Easy Way To Filter A Message Sender/Subject
   Mozilla currently does not have "filter by example", but there is a bug report.
