We care about your privacy. When SeaMonkey sends information to Mozilla, their privacy policy describes how they handle that information.
SeaMonkey automatically connects to Mozilla and their service providers to provide updates, security and other features.
Suite and add-ons updates
Suite Updates: Once per day, SeaMonkey sends the following info to Mozilla when it checks for suite updates: Your SeaMonkey version information, language preference, operating system and version. You can turn off updates by following the instructions you will find at Help > Customize SeaMonkey > Advanced Preferences > Software installation, but it may leave you open to security vulnerabilities.
Add-ons Blocklist: SeaMonkey contacts Mozilla once per day to check for add-on information to check for malicious add-ons. This includes, for example: Suite version, OS and version, locale, total number of requests, time of last request, time of day, IP address, and the list of add-ons you have installed. You can turn off meta data updates at any time by following the instructions you find at Help > Customize SeaMonkey > Advanced Preferences > Software installation, but it may leave you open to security vulnerabilities.
Security
SeaMonkey automatically checks for malicious or forged web pages, broken add-ons, and third-party issued SSL certificates.
Secure Website Certificates: When you visit a secure website (i.e. "https"), SeaMonkey will validate the website's certificate. This may involve communicating with a third-party status provider specified by the certificate. SeaMonkey sends to this third-party information identifying the site's certificate. You can change your preferences by following the instructions you find at Help > Internet Privacy > Privacy & Security Preferences > SSL, but if you disable the online verification feature, SeaMonkey cannot confirm the identity of the website you are visiting. Turning off this feature may increase the risk of your private information being intercepted. If you encounter an untrusted connection, you can also choose to send Mozilla the associated certificates.
SeaMonkey Safe Browsing: About twice per hour, SeaMonkey downloads Google's SafeBrowsing lists to help block access to sites and downloads that are malicious or forged (Google's privacy policy is at https://www.google.com/policies/privacy/). For downloaded executables that do not appear in these lists, SeaMonkey may send metadata, including URLs associated with the downloaded file, to the SafeBrowsing service. Visit https://support.mozilla.org/kb/how-does-phishing-and-malware-protection-work to learn more about or disable Safe Browsing. If you disable these features, SeaMonkey cannot warn you of potentially illegitimate or malicious websites or downloaded files.
Do Not Track Protection: About twice per hour, SeaMonkey downloads tracking protection lists from Disconnect.me to help block access to sites and resources that are known to track visitors browsing habits (Disconnect.me privacy policy is at https://disconnect.me/privacy). Visit https://support.mozilla.org/en-US/kb/tracking-protection-firefox to learn more about Tracking Protection feature. If you disable this feature, SeaMonkey cannot protect you from being tracked by those known sites.
When you ask it to, SeaMonkey also connects to Mozilla to provide you with features such as Sync, location services, crash reporting, and add-ons.
Sync: Firefox Sync is the brand name of a service that allows you to sync your SeaMonkey bookmarks, browsing history, passwords, and settings across all of your devices. If you use the Sync service, please read the Firefox Sync privacy notice.
Location services: SeaMonkey has a feature that allows sites to request your location (e.g., to allow those sites to show your location on a map). If a site requests your location, SeaMonkey seeks your permission before determining and sharing your location. In order to determine your location, SeaMonkey may use several pieces of data to determine your location, including your operating system's geolocation features, WiFi networks, cell phone towers or IP address. Estimating your location involves sending some of this information to Google's geolocation service, which has its own privacy policy.
Crash reporting: You have the option to send Mozilla a crash report in case SeaMonkey crashes. This report will contain technical information for us to improve SeaMonkey including why SeaMonkey crashed, the active URL at time of crash, and the state of computer memory during the crash. The crash report we receive may include personal information. We make portions of crash reports available publicly at http://crash-stats.mozilla.com/. Before publicly posting crash reports, we take steps to automatically redact personal information. We do not redact anything you may write in the comments box.
Add-ons: SeaMonkey contains a Get Add-ons page in the Add-ons Manager that features popular add-ons and displays personalized recommendations based on the add-ons you already have installed. To display the personalized recommendations, SeaMonkey sends information to Mozilla, including the list of add-ons you have installed, SeaMonkey version information, and your IP address. This communication only happens when the Get Add-ons area is open and can be turned off by following the instructions you find at Help > Advanced > Software Installation > Add-ons. The add-ons manager in SeaMonkey has a search field where you can enter keywords to perform searches and Mozilla collects these keyword searches, as well as your SeaMonkey version information, locale, and OS to show you recommendations.
