SessionBox Replacement
If you ended up here because the SessionBox extension stopped working, here is a short version of what happened, followed by an honest comparison of what is available now.
What happened to the extension
Chrome moved to new extension rules (Manifest V3), and every multi-session extension got caught by them — not just SessionBox. It is not about one product: the way these extensions swapped cookies inside a single tab simply has no place in the new rules.
SessionBox the company did not go anywhere: it moved people to SessionBox One — a separate application that does the same job, but outside the browser instead of inside it.
So the choice today is not "extension or nothing" — it is between applications. And Morfiade is as valid a choice here as SessionBox One.
The main difference
| Morfiade | SessionBox One | |
|---|---|---|
| What it is | a Windows program | an application that works with your browser |
| Browsers | Google Chrome only | Chrome, Firefox, Edge |
| Profiles on disk | as many as you create | unlimited on paid plans |
| Payment | subscription or once, forever | subscription, per seat |
| Team work | no | yes |
| Cloud profiles | no | yes, volume by plan |
| Own proxy per profile | yes | yes |
| Fingerprint spoofing | yes | not advertised on their side |
| Local API | yes, plus a bridge for AI agents | yes |
Where Morfiade is stronger
You can buy it once. SessionBox One is subscription only. We have a lifetime licence: pay once and the term never ends. This is the one thing no other product in this space offers.
Fingerprint spoofing exists. SessionBox One isolates profiles, but it does not advertise a consistent fingerprint — time zone, language and geolocation matching the proxy's country, canvas and WebGL noise. If you only need a separate session, you will not notice the difference. If your accounts need to look like they come from different machines, you will notice right away. What this actually is and when you really need it — in a separate breakdown.
Profiles are created in batches. Not one at a time through a menu, but a hundred at once: a prefix, a count, proxies handed out from a list. With a dozen accounts this does not matter; with a hundred and fifty it is the difference between an evening of work and a minute.
One action, instantly in every window. The synchroniser repeats what you do in the leading window across the rest, and the handout mode gives each window its own value from your list — and pins it to that profile. Repetitive forms stop being manual work.
The AI agent bridge lives inside the program. Morfiade connects to the agents you already have on your computer — Claude Code, Gemini CLI, Cursor and local models. The bridge lives inside the program itself and works with no internet and no separate packages.
The browser is genuine and it is yours. It launches the Chrome you installed from Google's site: the current version, your usual settings, your extensions.
Where SessionBox One is stronger
This is not politeness, it is the truth. If you need something from the list below, take SessionBox One rather than Morfiade.
Firefox and Edge. We only support Chrome, and this is not "for now" — the whole profile system is built around it.
Teams. Shared profiles, seats for employees, handing an account over without mailing files around. We do not have this at all.
Cloud profiles and work from several computers. With them a profile is available from another machine. With us it is export and import, by hand.
A direct upgrade path. If you worked with the SessionBox extension for years and want the same thing with the same habits, staying with them is the more logical move. We do not migrate their profiles automatically.
Who each suits
Morfiade — if you are on Windows, work alone, have a lot of accounts, want to pay once, and fingerprint spoofing would help you.
SessionBox One — if you need Firefox or Edge, work as a team, or move between computers.
Equally true of both
Neither product "gets around bans" or makes you invisible. Different sessions stop looking like the same person — that is all, and it is usually enough. If accounts still get banned despite careful isolation, the cause is almost always not the program but the proxy: an address from a known datacentre range collects captchas no matter what you cover it with. We tested this against live protection — switching to residential proxies helped, settings did not.
Frequently asked questions about replacing SessionBox
Why did SessionBox stop working?
Chrome moved to new extension rules (Manifest V3), and the way such extensions swapped cookies inside a single tab simply has no place in them. This affected not just SessionBox but every multi-session extension at once.
Is there a SessionBox-like extension that still works?
An extension that does it the old way, inside one tab, does not exist and cannot appear, for the reason above. The working replacement today is a separate profile per session: that is how both SessionBox One and Morfiade are built.
How is Morfiade different from SessionBox One?
SessionBox One is cloud-based: profiles live on their servers, and you get Firefox, Edge and team access. Morfiade is local: profiles live on your computer, Chrome only, but you get a proxy per profile, fingerprint spoofing and a one-time purchase instead of a subscription.
Will my SessionBox profiles transfer?
No. There is no automatic import of SessionBox profiles — you will need to sign in to the new profiles once by hand. After that, though, the sessions become transferable between computers.
Is it free?
There is a trial: 7 days and 100 profiles, no card required. After that it is a subscription or a one-time purchase — see pricing.
How many sessions of one site can I keep open?
As many as the machine can handle: each session is a separate Chrome window. The practical limit is RAM, not the program.
