# SeaMonkey Application: SeaMonkey Council Also called seamonkey suite, mozilla suite SeaMonkey Council, Browsers An application suite: browser plus MailNews from the old Mozilla suite. On Windows the process is seamonkey.exe. ## What you need to know SeaMonkey is a suite. It is not Firefox alone. The SeaMonkey Council ships browser plus MailNews as seamonkey.exe. Firefox is only a browser. Thunderbird is only mail. - **What is it?**: Internet suite **Still current?**: Yes, see Current status **Official download?**: Use the vendor link in this article Feex says If seamonkey.exe is open, I would look for MailNews in the same app. Closing firefox.exe does not quit SeaMonkey. ## What is SeaMonkey? SeaMonkey is the SeaMonkey Council suite: Navigator-style browser, MailNews, and Composer. The Windows executable is seamonkey.exe. ## If you have never used it If you want the old Mozilla suite idea, this is SeaMonkey: browser plus MailNews in one app. It is not Firefox alone. Download it from seamonkey-project.org/releases. The process is seamonkey.exe. Thunderbird plus Firefox is a different pair of products. ## What is it used for? **Browse in the suite browser** The web window is one part of SeaMonkey. It is not a standalone Firefox profile. **MailNews** Mail and newsgroups live in the same app. Thunderbird is a different exe. **Composer** A leftover HTML editor from the suite era. It is not Word and not VS Code. ## Who is it for? - People who still want a Mozilla-style suite - Users migrating old SeaMonkey MailNews profiles - Anyone who searched Firefox and landed on this suite ## Current status SeaMonkey (2005) is a current internet suite from SeaMonkey Council. The vendor still points Windows users at https://www.seamonkey-project.org/releases/. ## How old is it? SeaMonkey 1.0 shipped in 2005 as the community continuation of the Mozilla Application Suite. It is younger than Netscape Communicator and older than most Chromium browsers. Current SeaMonkey is still a suite, not a Firefox reskin. ## Versions Major channels first. Exact build numbers are not all verified here. Current Windows build ## System requirements Values follow the publisher's public guidance. Workload still changes the real need. ### Minimum | Operating system | A current supported Windows 10 or Windows 11 release, per the vendor | | ---------------- | -------------------------------------------------------------------- | | RAM | Enough for Windows plus this app. Heavy projects want more. | ## Resource profile - **CPU demand**: Follows what you open inside the app **RAM demand**: Follows documents, tabs, or libraries ## Installed processes These executables belong to this product when it is installed. | seamonkey.exe | Main Windows executable | | ------------- | ----------------------- | ## Startup components SeaMonkey can open mail at launch. That is a suite option, not a Windows mail service. ## File locations | Typical install | C:\Program Files\SeaMonkey\\ | | --------------- | ---------------------------- | ## File formats HTML, EML, MBOX ## Common problems ### Modern web and mail defaults feel old The suite moves slower than Firefox Rapid Release. That is expected, not a failed install. ### People uninstall Firefox to remove mail SeaMonkey mail is inside seamonkey.exe. Firefox does not host it. ## Getting unstuck ### Confirm seamonkey.exe, not firefox.exe The suite lives under SeaMonkey. Mozilla Firefox is a different folder. ### Use SeaMonkey project docs for MailNews Thunderbird help will name the wrong profile path. ### Install from seamonkey-project.org/releases A SeaMonkey gold listing is junk. ## Alternatives Firefox plus Thunderbird if you want separate modern apps. Pale Moon if you want an independent browser without MailNews. ## Official help and downloads Start with the vendor. Random exe sites are not a support channel. | Download | [www.seamonkey-project.org/releases/ ](https://www.seamonkey-project.org/releases/)Official installer or vendor page | | ------------- | -------------------------------------------------------------------------------------------------------------------- | | Help | [www.seamonkey-project.org/doc/ ](https://www.seamonkey-project.org/doc/)Vendor support | | Official site | [www.seamonkey-project.org/ ](https://www.seamonkey-project.org/)Start here, not a random exe host | ## Related hardware RAM follows open mail plus tabs.
