SeaMonkey Privacy Policy

We're working hard to protect your privacy while delivering products and services that bring you the performance and protection you desire in your personal computing. This privacy policy explains how Mozilla Foundation ("Mozilla"), collects and uses information about users of the official SeaMonkey Internet suite ("SeaMonkey"). It does not apply to other Mozilla websites, products or services.

Types of Information

As with most Internet products, SeaMonkey sends certain information to the websites that you visit. This information falls into the following categories:

Information SeaMonkey Sends to Websites

Like most web browsers, SeaMonkey sends information to the websites you visit, including (1) Non-Personal Information of the type that web browsers typically make available, such as the type of browser you are using, your language preference, the referring site, and the date and time of your visit; and (2) Potentially Personal Information such as your IP address. This information may be logged on the websites you visit. What information is logged and how that information is used depends on the policies of each of the websites you visit.

Each website determines its own privacy policy for the distribution and use of this Non-Personal Information and Potentially Personal Information. If you are concerned about how a website will use this information, check out its privacy policy. To find out more about how Mozilla uses this information on its own websites, see the Mozilla Privacy Policy.

Interactive Product Features

Crash-Reporting Feature. SeaMonkey has a crash-reporting feature that sends a report to Mozilla when SeaMonkey crashes. Mozilla uses the information in the crash reports to diagnose and correct the problems in SeaMonkey that caused the crash. Though this feature starts automatically after SeaMonkey crashes, it does not send information to Mozilla until you explicitly authorize it to do so. By default, this feature sends a variety of Non-Personal Information to Mozilla, including the stack trace (a detailed description of which parts of the SeaMonkey code were active at the time of the crash) and the type of computer you are using. Additional information is collected by the crash reporting feature. Which crash reporting feature is used and what additional information collected by SeaMonkey depends on which version of SeaMonkey you're using.

SeaMonkey 1.x.

These earlier versions of SeaMonkey don't include a crash reporting feature at all, no information about crashes is sent to Mozilla at any time.

SeaMonkey 2.x.

For the current versions of SeaMonkey, "SeaMonkey Crash Reporter" is SeaMonkey's crash reporting feature. With this feature, you have the option to include the URL of the site you were visiting when SeaMonkey crashed, a comment, and your email address in the report. SeaMonkey Crash Reporter also sends a list of all add-ons that you were using at the time of the crash, the time since (i) the last crash, (ii) the last install, and (iii) the start-up of the program. Mozilla only makes Non-Personal Information (i.e., generic information about your computer, the stack trace, and any comment given by the user) in the public reports available online at

To safeguard your privacy, Mozilla makes the Personal Information, such as your name and email address, and Potentially Personal Information, such are the URL of the site you last visited, only available to its employees, contractors, and selected contributors who signed confidentiality agreements that prohibit them from using or disclosing such information other than for internal Mozilla purposes.

Report Broken Web Site Feature. SeaMonkey's Report Broken Web Site feature lets you notify Mozilla when a website you visit improperly displays or incorrectly functions. The feature sends the URL of the broken website to Mozilla. You may also choose to send your email address and a description of the problem. This feature also sends a variety of Non-Personal Information to Mozilla, including but not limited to the version of SeaMonkey you are using and your language preference. Except for your email address, Mozilla makes all of this information public. This feature does not send information to Mozilla until you explicitly authorize SeaMonkey to do so. To prevent this public release of Personal and Potentially Personal Information, don't report a website if the website's URL contains your Personal and Potentially Personal Information, and don't include Personal Information in your description of the problem. To prevent the release of any information, don't use this feature to report a broken website.

Automated Update Service. SeaMonkey's automatic update feature (only included in SeaMonkey 2.x) periodically checks to see if an updated version of SeaMonkey and installed add-ons are available from Mozilla.


This feature sends Non-Personal Information to Mozilla, including the version of SeaMonkey you are using, build ID and target, update channel, your operating system, and your language preference. This feature also sends Potentially Personal Information to Mozilla in the form of a cookie named "aus" that contains a unique numeric value to distinguish individual SeaMonkey installs. Mozilla uses this information to provide you with updated versions of SeaMonkey and to understand the usage patterns of SeaMonkey users. We use this information to improve our products and services and to support decision making regarding feature and capacity planning.


The add-ons update version check sends Non-Personal Information to Mozilla, including the version of SeaMonkey you are using, version of the add-ons you have installed, build ID and target, update channel, your operating system, and your language preference with each check of an add-on that uses as its update host. If any of your add-ons use a third party update URL, SeaMonkey will check that URL for updates to those add-ons.

We do not collect or track any Personal Information or any information about the Web sites you visit, and we do not release the raw information we obtain from these features to the public. We may release reports containing Aggregate Data so that our global community can make better product and design decisions. To prevent Mozilla from obtaining this information, you can turn this feature off in SeaMonkey's preferences (in the Advanced > Software Installation panel).

SeaMonkey 1.x includes an update notification instead of the Automated Update Service used in SeaMonkey 2.x. The notification only requests a web document from the SeaMonkey website (the usual Non-Personal Information listed in the Websites topic of this page is sent, but nothing else). SeaMonkey then determines if the installed version is older than the one offered on the website, and if so, displays an update notification.

Add-ons Features. One thing that makes SeaMonkey so flexible is the ability for you to add various add-ons, extensions, and themes to SeaMonkey, thereby creating a custom browser that fits your needs. The following features show how SeaMonkey 2.x provides both the ability to obtain additional add-ons easily and to protect against potentially harmful add-ons.

Get Add-ons Feature

SeaMonkey 2.x offers a Get Add-ons Feature. This feature creates a list of recommended add-ons and extensions to try. You access this recommended list by clicking on the "Get Add-ons" tab from the SeaMonkey Add-ons Manager. We do not collect any Personal Information. To display the recommended list, SeaMonkey sends Non-Personal Information to Mozilla, including the type of computer and version of SeaMonkey you are using as well as any cookies set by

Blocklist Feature

SeaMonkey 2.x also offers a Blocklist feature. With this feature, once a day SeaMonkey does a regularly scheduled, automatic check to see if you have any harmful add-ons or plug-ins installed. If so, this feature disables add-ons or plug-ins that Mozilla has determined contain known vulnerabilities or major user facing issues or fatal bugs (e.g., client crashes on startup or something causing an endless loop of unusability). You may view Firefox's current list of Blocklisted items, SeaMonkey's list is a subset of those, blocking only those that affect SeaMonkey in any way. This feature sends Non-Personal Information to Mozilla, including the version of SeaMonkey you are using, operating system version, build ID and target, update channel, and your language preference. In addition, Mozilla also uses this feature to count the number of active SeaMonkey users. Currently there is no basic user interface to disable the Blocklist feature. An article in the Firefox Knowledge Base explains how you may disable the Blocklist feature, this explanation holds true for SeaMonkey as well. Disabling the Blocklist feature is not recommended as it may result in using extensions know to be untrustworthy. More information about the Blocklist feature may be found at

Location-aware Feature

SeaMonkey 2.x offers a Location-Aware Feature, parts of which may be provided by third party service providers.

You Elect to Use the Location-Aware Feature

This feature remains inoperative until you visit a website that requests your location and you choose to opt in to the feature. If you elect not to, nothing happens. Each time you visit such a website, SeaMonkey asks you if you want it to provide the site with your current location. Additionally, you may elect to have SeaMonkey remember your choice to allow or not allow the feature for each site. Any such election is domain specific. You are able to opt out at any time of having SeaMonkey remember your choice, just like any other preference setting.

What Information SeaMonkey Collects

If you choose to allow it, the SeaMonkey Location-Aware Feature first collects one or more of the following relevant location markers: (i) location provided by a GPS device built into or attached to your computer or device and/or geolocation services provided by the operating system; (ii) the wifi routers closest to you; (iii) cell ids of the cell towers closest to you; (iv) the signal strength of nearby wireless access points and/or cellular phone towers; and/or (v) your computer or device’s IP address. Next, it attempts to determine your location using these location markers. Any information SeaMonkey uses, receives or sends as part of this Location-aware Feature is not received by any Mozilla servers or by Mozilla. SeaMonkey does not track or remember your location. SeaMonkey does remember a random client identifier, the temporary ID assigned by our third party provider to process your request, for two weeks.

What Information Third Parties Receive & Provide

If necessary, SeaMonkey sends the information above, except any GPS information and/or geolocation data provided by the operating system, plus you user agent information (e.g, version of SeaMonkey you're using), along with a temporary client identifier, to its third party service provider(s) capable of deriving a physical location from the information SeaMonkey has collected (e.g., convert a set of WiFi signal strengths into latitude and longitude). This information is sent over an encrypted connection. The connection between SeaMonkey and the service provider does not use any cookies. Neither the domain name nor the URL of the site you’re visiting are sent to our service providers. Our providers estimate your location and return it to SeaMonkey. SeaMonkey provides your location information to the webpage that made the request. For any information the webpage sends back to the website, please see that website's privacy policy.

Third Party Websites

Please carefully consider any website's privacy practices before agreeing to share your location with that website.

  • Requesting Websites. For any information the webpage sends back to the website, please see that website's privacy policy.
  • Location-aware Service Providers. In addition, our service providers have their own privacy policy.
  • ISP and Mobile Carrier. All requests must be sent through your internet service provider or mobile carrier network and your service provider or carrier may have access to the request. For information regarding your service provider's or carrier's treatment of your information, please consult their privacy policies.

For more information, please see Learn More for this feature.

Security Features

Secure Website Certificate Verification. When you visit a secure website, SeaMonkey will check with the certificate provider to validate that website's certificate. SeaMonkey sends only the certificate identification to the certificate provider, not the exact URL you are visiting. If the certificate is not valid, you will receive an error page that states the certificate was revoked and you will not be able to access that website. The technical name for this process is OCSP or On-line Certificate Status Protocol. You may completely turn off the secure website certificate verification feature in SeaMonkey's preferences under the Validation panel in the Privacy & Security category. If you do this, none of the information discussed here will be sent to any third party certificate provider.


A cookie is a small string of information that a website stores on your computer and that web browsers make available to that website each time you return. SeaMonkey stores cookies on your computer when requested to do so by websites. A website uses cookies to help identify and track visitors, the use of the website, and visitors' website access preferences across multiple requests and visits. It is possible to include Personally-Identifying Information, or references to such information, in cookies, thereby enabling websites to track the online movements of particular individuals. To prevent SeaMonkey from sending cookies to specific websites, configure SeaMonkey to prompt you when a website wants to set a cookie. To prevent SeaMonkey from sending cookies to any website, configure it to disable cookies.

Privacy Policy Changes

Mozilla may change the SeaMonkey Privacy Policy from time to time. Any and all changes will be reflected on this page. When Mozilla changes this policy in a material way, a notice will be posted on the Web site. Substantive changes may also be announced through the standard mechanisms by which Mozilla communicates with its users and community, including Mozilla's "announce" mailing list and newsgroup. It is your responsibility to ensure that you understand the terms of this Privacy Policy. You should periodically check this page for any changes to the current policy.
