Mozilla features

The following list is my impression of the most important enhancements of the Mozilla Suite (now called SeaMonkey) as compared to Netscape 4.X. A website comparing Mozilla's features with IE is somewhere else. Mozilla.org themselves also have some pages explaining why somebody would want to use Mozilla.

  1. It is Open Source. That means in principle you can fix all the bugs that you find yourself.
  2. It is more stable than Communicator 4.X.
  3. Mozilla has all recent security fixes.
  4. It has support for all current standards like XML, MathML (on some platforms), XHTML, HTML 4.01, CSS 1+2, etc.
  5. Mozilla has a nicer, fully customizable interface (using "Themes", the XUL language, JavaScript and CSS).
  6. Under Unix it will adapt to the current GTK interface theme when using Classic theme. On OS/2 it will also use the fonts used in PM programs.
  7. It allows to install packages for other languages, Themes, and add-on tools and enhancements (see e.g. MNG/JNG support above).
  8. Uses notebook-like "tabs" to display several webpages within one browser window.
  9. You can have a group bookmarks which are load all the pages in different tabs.
  10. An internet search engine of your choice can be integrated into the URL bar.
  11. A document navigation bar using the "link rel" tags in the HTML code. Switch it on under View->Show/Hide->Site Navigation Bar.
  12. The "sidebar" can display bookmarks, the browsing history, search engine output, and news tickers.
  13. It supports "favicons" in any image format.
  14. Full support for PNG (alpha transparency), JNG (JPEGs with transparency), and a subset of animated MNG images was added. (For MNG/JNG support after version 1.4.x see builds page.)
  15. Mozilla has the ability to save form information on webpages, passwords for logging into sites.
  16. and it can encrypt saved information before it is saved to disk.
  17. It can block unwanted images, cookies, popup windows, and some annoying JavaScript instructions.
  18. Mozilla can automatically resize images which do not fit in the browser window.
  19. It can save whole webpages to disk (with all images etc. included!).
  20. It has some features to enhance performance of HTTP networking.
  21. Link Prefetching means that it can automatically pre-load stuff while you are reading a page.
  22. Rich text editing controls in webpages, called Midas.
  23. It adds a chat component Chatzilla.
  24. Multiple user profiles are supported and can be switched on the fly.
  25. You can now also have multiple POP/IMAP inboxes.
  26. A somewhat "intelligent" junkmail filter mechanism for emails.
  27. Keyboard navigation, allowing to find links and text while typing.
  28. Smooth scrolling when using the keyboard to scroll.
  29. You can have a group of homepages which are loaded in several tabs.
  30. A download manager, keeping a history of all files loaded from the web, is included.
  31. On OS/2 you can Ctrl-Drag to save images and webpages to WPS folders via drag-and-drop.
  32. On OS/2 Mozilla can used smooth font display via antialiasing from the InnoTek Font Engine. The same is possible on Linux with GTK2.
  33. A Calendar component
  34. New web development tools: the DOM Inspector and "Venkman" JavaScript Debugger.

Unfortunately, Mozilla also needs much more RAM than older browsers, easily 40MB and up to 100MB and more after a few hours of internet browsing.

The feature set of the standalone Mozilla product, the Firefox browser and the Thunderbird Mail- and Newsclient, is comparable to the above, but for some features one has to install extra extensions.
