Safari to Mozilla Firefox converter

Safari and Mozilla Firefox both use CSV, but Safari writes 6 columns; Mozilla Firefox expects 3 in a different order — so Firefox rejects a raw Safari export or silently files everything into the wrong fields. Drop your export below and get back a file Firefox accepts.

Convert your Safari export

Drop your Safari CSV here or click to choose a file — nothing is uploaded

The conversion runs entirely in this tab using JavaScript. Your file is never sent to a server — you can confirm it by opening your browser's Network tab, or by turning off Wi-Fi before you drop the file in. Prefer not to do this in a browser tab at all? Download the converter and run it from your own disk.

Your export file is plaintext. Both the file Safari gives you and the one you download here contain every password in readable form. Delete them as soon as the import is verified, and empty your trash.

What's actually different between the two formats

Not one column name matches between the two formats (Title, URL, Username… versus "url", "username", "password"…), which is why a direct import fails.

Safari column	Mozilla Firefox column	What happens
`Title`	`— none —`	Firefox has no item name field. Written into notes instead of dropped.
`Username`	`username`	Renamed and repositioned
`Password`	`password`	Renamed and repositioned
`URL`	`url`	Renamed and repositioned
`OTPAuth`	`— none —`	Firefox has no 2fa secret field. Written into notes instead of dropped.
`Notes`	`— none —`	Firefox has no notes field. Written into notes instead of dropped.

What carries over

Field	Safari	Firefox	Result
Item name / title	Yes	No	Firefox identifies logins by URL only, so titles are dropped.
Username and password	Yes	Yes	Carried over
Website URL	Yes	Yes	Carried over
Notes	Yes	No	Dropped — the target has no notes field.
Folders / groups	No	No	Not in the source file
Two-factor (TOTP) secrets	Yes	No	Written into notes. Re-add them by hand, or keep them in a separate authenticator.
Favorites	No	No	Not in the source file
Custom fields	No	No	Not in the source file
Multiple URLs per entry	No	No	Not in the source file
File attachments	No	No	Not in the source file

Step 1 — Export from Safari

On macOS Sequoia or later, passwords moved to the Passwords app — open that instead of Safari.
On earlier macOS: Safari → Settings → Passwords, then the ••• button → Export All Passwords.
Confirm with Touch ID or your Mac login password.
Save the CSV.

Watch out for

Safari and the Passwords app share one iCloud Keychain store and one CSV layout — importing to either lands in the same place.
There is no folder structure in iCloud Keychain, so groups from the source have to go into notes.

Step 2 — Convert it

Drop the file onto the converter above. It parses Safari's layout, maps each field onto the universal record, then writes Mozilla Firefox's exact expected columns — including the empty ones its importer requires and, where the two differ, the right shape for 2FA secrets. You'll see a preview and a list of anything Firefox can't hold before you download.

Rather not put this file in a browser tab connected to the internet? The same converter is available as a single HTML file you can download and open with your network switched off.

Step 3 — Import into Mozilla Firefox

Go to about:logins in Firefox.
Open the ••• menu → "Import from a File…".
Choose the converted CSV.

Watch out for

Firefox has no concept of a title, folder, note or TOTP secret. Entries are identified by URL alone, so an entry name has nowhere to go.
Firefox writes its header names in quotes ("url","username",…). Some importers choke on that; the converter normalizes it.

Step 4 — Verify and clean up

Open ten entries in Mozilla Firefox at random and check them against Safari.
Sign in to one real site using Mozilla Firefox to confirm autofill works.
Delete both CSV files and empty your trash. If your Downloads folder syncs to iCloud, OneDrive or Dropbox, confirm the deletion propagated there too.
Only then close your Safari account — and change any password you suspect was exposed while the plaintext file existed.

Questions

Why won't Mozilla Firefox import my Safari file directly?

Not one column name matches between the two formats (Title, URL, Username… versus "url", "username", "password"…), which is why a direct import fails. The converter rewrites the file into Mozilla Firefox's exact expected layout, including the column order and any empty columns its importer requires.

Do my passwords get uploaded anywhere?

No. The conversion is JavaScript running in your own browser tab — the file is read with the FileReader API, transformed in memory, and handed back to you as a download. There is no upload, no server-side processing and no analytics attached to the file. You can verify this by disconnecting from the internet before you drop the file in: the conversion still works.

What gets lost moving from Safari to Mozilla Firefox?

Mozilla Firefox can't natively store: item name / title, notes, two-factor (totp) secrets. Rather than drop that data, the converter writes it into the notes field where Firefox has one, so you can move it back by hand. Keep your Safari account active until you've confirmed everything you need made it across.

Can I keep my 2FA codes in Mozilla Firefox?

No — Mozilla Firefox has no field for TOTP secrets at all. The converter puts each secret into the entry's note so it isn't lost, but Firefox won't generate codes from it. Move those to a dedicated authenticator app before you shut down Safari, or pick a target that supports them.

Is the export file from Safari encrypted?

No. A Safari CSV export is plaintext — every password in it is readable by anything that can open the file, including other apps on your machine and anything that syncs your Downloads folder to the cloud. Convert it, import it, then delete both files and empty your trash. If your Downloads folder syncs to iCloud, OneDrive or Dropbox, check that the deletion propagated.

Anything unusual about Safari's export?

Safari and the Passwords app share one iCloud Keychain store and one CSV layout — importing to either lands in the same place.

Anything unusual about importing into Mozilla Firefox?

Firefox has no concept of a title, folder, note or TOTP secret. Entries are identified by URL alone, so an entry name has nowhere to go.
