About Proofsnap and Firefox Sync

In their own words, as submitted to SaaSHub.

Proofsnap
Firefox Sync

ProofSnap preserves a web page, social media post or chat as a signed evidence package. It works as a browser extension for Chrome and Edge, and as a REST API with a web dashboard for teams that capture at scale.

Features and specs

What each product offers, as listed by its team.

Proofsnap 5 features
Firefox Sync 5 features
  • Signed evidence package
    Every capture becomes a package of 11 to 15 files: full-page screenshot, page source, extracted text, metadata, HTTP headers, DNS and WHOIS records, with a SHA-256 hash of every file and an RSA-4096 signed manifest.
  • Independent timestamps
    The manifest hash is anchored in Bitcoin via OpenTimestamps on most plans, and an eIDAS qualified timestamp from a Qualified Trust Service Provider on the EU Trusted List is optional.
  • Offline verification without the vendor
    Anyone, including the other side, can check the hashes, signature and timestamps offline with the bundled scripts or the open-source verifier, without relying on ProofSnap.
  • Chat and AI conversation capture
    Captures full conversations in WhatsApp Web, Telegram, Discord and Slack, and chats in ChatGPT, Gemini and Claude, including the parts that need scrolling.
  • Multi-tab sessions with video
    Records a browsing session across several tabs, with a separate forensic snapshot of each visited tab and a session video, all in one signed package.
  • Cross-Device Synchronization
    Firefox Sync allows users to synchronize their bookmarks, history, passwords, and open tabs across multiple devices, providing a seamless browsing experience.
  • Privacy and Security
    Mozilla is known for its strong stance on user privacy. Data synchronized through Firefox Sync is end-to-end encrypted, ensuring that user information remains secure and private.
  • User Control
    Users have full control over what data is being synchronized. Only selected types of data such as bookmarks, history, passwords, or open tabs are synced based on user preferences.
  • Open Source
    As an open-source project, Firefox offers greater transparency and the community-driven development often leads to robust security and regular updates.
  • Easy Setup
    Setting up Firefox Sync is straightforward and user-friendly, requiring just a few steps to get started.

Possible disadvantages

  • Dependent on Firefox
    Firefox Sync is limited to Firefox browsers. Users who want to switch between different browsers other than Firefox will not be able to fully utilize its syncing features.
  • Performance Issues
    Some users have reported occasional performance issues such as lag during synchronization or increased memory usage.
  • Account Required
    Users must create a Firefox Account to use Firefox Sync, involving an extra step that might be seen as an inconvenience by some.
  • Limited to Firefox Data
    Firefox Sync only syncs data related to the browser (e.g., bookmarks, history, settings). Other types of data or applications are not supported.
  • Recovery Challenges
    If users forget their Firefox Account password and don't have recovery keys, accessing synchronized data can be challenging due to the strong encryption methods used.

Questions & Answers

As answered by people managing Proofsnap and Firefox Sync.

Which are the primary technologies used for building your product?

Proofsnap's answer

ProofSnap was built in Dubai and is registered in Sharjah (SHAMS). It started from a simple observation: online content that matters in a dispute is usually saved as a screenshot, and a screenshot is the easiest kind of record to challenge. ProofSnap captures the page together with the cryptographic proof of what was captured and when, so the record can be checked rather than argued about.

ProofSnap captures the page together with the cryptographic proof of what was captured and when, so the record can be checked rather than argued about.

Why should a person choose your product over its competitors?

Proofsnap's answer

Verification does not depend on a vendor portal or account: the other side can check the hashes, signature and timestamps offline with standard tools. ProofSnap also covers what many web capture tools skip: full chat conversations (WhatsApp Web, Telegram, Discord, Slack, ChatGPT, Gemini, Claude), multi-tab sessions with video, and an optional eIDAS qualified timestamp. It works as a browser extension with no setup, and a one-off SnapPack is available for people with a single matter.

How would you describe the primary audience of your product?

Proofsnap's answer

Lawyers and paralegals, private and corporate investigators, OSINT researchers, journalists, compliance and HR teams, brand protection teams, and individuals who need to preserve online content (posts, profiles, listings, chats) before it is edited or deleted.

What makes your product unique?

Proofsnap's answer

Every capture is a self-contained evidence package that anyone can verify without us. The package holds the screenshot, page source, metadata, HTTP headers, DNS and WHOIS records, a SHA-256 hash of every file, an RSA-4096 signed manifest and an independent timestamp, and it ships with verification scripts and an open-source verifier. If ProofSnap disappeared tomorrow, the packages could still be checked.
