Killed by Mozilla is an informational website that catalogs Mozilla projects that have been shut down, discontinued, or are scheduled for retirement. It covers a range of projects including Orbit, Pocket, Fakespot, Firefox Send, Firefox OS, Mozilla Persona, XULRunner, Mozilla Prism, and others, listing approximate years of operation, product positioning, and some reasons for shutdown. It is not a SaaS product or enterprise software in the traditional sense; it is closer to a historical archive of open-source community and internet product activity.
The site’s core function is to present the lifecycle of Mozilla projects in individual entries. Each project typically includes its name, year range, a brief description, and background on why it was discontinued. For example, Orbit was a Firefox extension that used a Mozilla-hosted Mistral 7B instance on GCP to summarize emails, articles, and videos; Firefox Send was an end-to-end encrypted file-sharing service that was suspended and shut down due to abuse; Mozilla Persona was a decentralized single sign-on system that was discontinued due to low adoption. Overall, the site is useful for quickly looking up changes across Mozilla’s product portfolio.
The content does not mention plans, pricing, payment methods, free trials, or enterprise subscriptions, so its business model cannot be evaluated from a SaaS procurement perspective. The bottom of the site provides “Source code: sr.ht,” suggesting that the source code may be public, but the content does not describe deployment documentation, self-hosting options, APIs, webhooks, or SDKs. Enterprise capabilities such as team collaboration, permission management, auditing, security, and compliance are also not disclosed.
Its strengths are high information density and broad coverage. It brings together multiple discontinued Mozilla projects—from browser extensions and web services to developer tools and operating systems—on a single page, making it convenient for studying product lifecycles and strategic trade-offs. Its limitations are that it is not a business system and lacks common enterprise knowledge-base features such as search, filtering, data export, and collaborative annotation. Some entries also have incomplete years or shutdown reasons, so it should be treated as a starting point for research rather than a replacement for official announcements or deeper investigation.
It is suitable for developers, product managers, open-source researchers, and observers of the browser ecosystem who want to understand Mozilla’s historical projects and why they were discontinued. The content does not provide information about access from China, so it is not possible to determine whether it can be reached directly; there is also no payment-related information. Alternative sources include Killed by Google, Wikipedia, the Mozilla official blog, project repositories, and news announcements. If a company needs a formal knowledge base or competitive intelligence system, more complete collaboration tools such as Notion, Confluence, 飞书知识库, or 语雀 would be better choices.
