SeaMonkey for Mac is the all-in-one internet application suite formerly known as the "Mozilla Application Suite", Containing an Internet browser, email & newsgroup client with an included web feed reader, HTML editor, IRC chat and web development tools, SeaMonkey for macOS is sure to appeal to advanced users, web developers and corporate users.

Features and Highlights

Sync allows you to keep your browsing history, passwords, bookmarks, preferences and tabs in sync across different devices (computers) in a secure way.

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.

Session restore brings back all your open windows and tabs after the rare occasion that SeaMonkey crashes—and if you wish even when you close and reopen the web browser or restart your computer.

Add-ons Management provides almost infinite possibilities to extend your Internet experience both through installing additional functionality created by others and even freely developing your own extensions and providing them to the rest of the app community.

Feed detection notifies you when web pages offer RSS or Atom feeds, and feed preview lets you view their contents and choose a reader with which to subscribe to those - including an internal reader in the Mail & Newsgroups component of the tool.

Tabbed Mail lets you manage your mail and folders in parallel, without losing control of where you're at when reading, replying to and working with messages in more complex patterns.

Junk mail controls help you take back control of your e-mail from spammers. The app's adaptive junk mail control gets smarter with use and is personalized to the e-mail that you receive.

Chat on IRC networks with this simple yet powerful IRC client. Multiple networks and channels are easy to keep track of in a familiar tabbed interface.

DOM Inspector enables you to dig into the document structure of web pages, add-ons or even the SeaMonkey "chrome" itself and inspect a huge number of properties of any element in that structure, including JavaScript objects and CSS styles.

JavaScript Debugger ("Venkman") lets you debug JavaScript code on your websites, add-ons and even in Sea Monkey for Mac itself with a suite of powerful debugging tools.

Also Available: Download SeaMonkey for Windows
