Can I import cookies.sqlite into this converter?

No. Paste Netscape or JSON text. SQLite is a different schema and is not a supported format.

Will Firefox SameSite values survive a cookies.txt export?

Not through Netscape. If Cookie Quick Manager’s JSON export includes SameSite, paste JSON instead of cookies.txt.

Is this an official Cookie Quick Manager page?

No. It is a conversion guide for files that extension can emit. Use Cookie Quick Manager itself to read the Firefox jar.

Cookie Quick Manager Export to JSON

Convert Cookie Quick Manager exports to JSON

Cookie Quick Manager is a Firefox extension that exports cookies as Netscape or JSON; paste that export here to produce a JSON array you can import in Chrome with CookieMan. This is not the Cookie Quick Manager site, and a web page cannot read Firefox’s cookies.sqlite.

Prefer the extension’s Netscape or JSON export over copying a request header. Header-only copies lose Domain and HttpOnly.

1
Export from Cookie Quick Manager
In Firefox, export the site’s cookies as Netscape cookies.txt or as JSON. Avoid CSV unless you are ready to rebuild seven Netscape fields by hand.
2
Convert to JSON Array
Paste the file below. Netscape becomes JSON with httpOnly taken from #HttpOnly_. If you already exported JSON objects, detection keeps them.
3
Import in Chromium
Install CookieMan in Chrome or Edge, open the same origin, Import → preview → Apply. Host-only versus dotted domains must match what Firefox stored.

Cookies are credentials. Conversion stays in this page — delete the file when you are done.

Firefox jar to Chrome jar — what still breaks

A transferred cookie is necessary, not sufficient. Sites that bind the session to user-agent, IP or a device token will still log you out. Partitioned CHIPS cookies from Chrome will not appear in a Firefox Netscape dump. __Host- cookies must keep Secure, Path=/ and no Domain or Chrome rejects them — fix __Host- rejected.

CookieMan runs on Chromium. It will not load as a Firefox extension. The conversion is the bridge; the live editor is Chrome/Edge.

Leading dots and host-only

Netscape column 2 TRUE means “include subdomains” (not host-only). CookieMan JSON stores the inverse as hostOnly. If a session works on www.example.com but not app.example.com, you imported a host-only cookie. Compare the flag before you blame the server.
