About SeaMonkey

SeaMonkey is a free, open source, and cross-platform Internet suite that is the continuation of the former Mozilla Application Suite. SeaMonkey is community-driven, in contrast to the Mozilla Application Suite, whose stable 1.7 branch remains governed by the Mozilla Foundation.

SeaMonkey Features

  • Tabbed browsing gives you a better way to surf the net. You no longer have to open one page at a time. With tabbed browsing, open several pages at once with one click. Plus, your homepage can be multiple pages, in tabs.
  • Popup blocker lets you surf the web without interruption from annoying ads.
  • Image Manager lets you block images to remove offensive images or speed up the rendering of web sites.
  • Find as you type gives you another way to navigate a page. Just start typing to jump from link to link or to find a word or phrase within a page.
  • Manage your mail with customizable Labels and Mail Views.
  • SeaMonkey's powerful yet simple HTML editor keeps getting better with dynamic image and table resizing, quick insert and delete of table cells, improved CSS support, and support for positioned layers.
