Firefox Send was a Mozilla service for sharing encrypted files through temporary links. Mozilla discontinued it in 2020, so it should not be treated as a current recommendation.
What made the service notable
Send combined browser-based file sharing with expiration controls and optional password protection. Its design illustrated how a simple interface could give users more control over how long a shared file remained available.
Why historical product status matters
Articles about technology can remain online after a service closes. Before depending on any tool, confirm that it is active, maintained and supported by a trustworthy organization.
How to evaluate a current alternative
Review encryption, recipient authentication, expiration, storage location, file-size limits, audit controls and the provider’s privacy and retention policies. Business use may require contractual and regulatory safeguards beyond a consumer feature.
The durable lesson from Firefox Send is that convenient sharing should still minimize exposure and give the sender meaningful control over access.
