Firefox Send was beloved: upload a file, get a self-destructing link, done. No account, encrypted, auto-expiring. Mozilla discontinued it in 2020 after abuse concerns. Six years on, people still search for it. Here are the closest replacements in 2026.
Any worthy successor needs most of these traits: zero friction, automatic expiry, and a privacy-first posture.
fff files is the closest match to Firefox Send's ethos. No account, drag-and-drop upload, and every file auto-deletes on a size-based schedule (7-90 days). No cookies, no IP logging, files stored encrypted at rest on Cloudflare R2. It even supports clipboard paste for screenshots. Free, 250MB limit.
If you loved Firefox Send for its simplicity, prioritize tools that don't force an account and that expire files automatically. If encryption was the draw, verify whether encryption is end-to-end (in your browser) or at-rest (on the server) — they protect against different threats.
Firefox Send isn't coming back, but its spirit lives on. For no-account, auto-expiring, privacy-respecting sharing, fff files is the most direct spiritual successor.
