Firefox alternative: how do I replace Firefox with a portable browser?

Mozilla still ships a classic desktop browser. You run an installer, you get a profile on the machine, and advanced users end up in hidden settings because Firefox remains a large, customizable suite. Independence from Google is real, but it is neither a 15 MB folder nor native ASIO. Capsule offers something else: about 15 MB to copy to USB or SSD, no administrator password, and Komby Limited’s zero-tracking stance. Audio goes through a built-in bridge rather than the Web Audio sandbox shared by classic browsers. This page is about Mozilla’s shape — installed, customizable, and still not a stick.

Why Capsule is a better fit than Firefox for portable work

Size as a product choice from day one

Firefox is a large desktop application. Once you count the installer and the unpacked tree, you are in a different weight class from Capsule’s 15 MB payload. The whole Capsule browser is that 15 MB — not a stub that downloads the rest later. Size here is what fits on a stick, what clones to a second machine quickly and what restores after a wipe without waiting on Mozilla’s update channel. If you already carry tools on USB, Capsule sits next to a small utility; Firefox sits next to an office suite. The product is designed as a file rather than as a channel you babysit.

An installed suite versus a native portable

Firefox expects an installation. Unofficial “portable Firefox” packs are usually a conversion of software designed to be installed — a third-party wrap, not a native portable architecture. Capsule is built to run from a folder. Copy it to USB, an external SSD or a local disk; there is no installer, no admin rights and no registry ceremony. That model fits locked office PCs, hotel machines, club computers and any Windows, Mac or Linux box where you cannot write into Program Files. When you unplug, you take the folder with you instead of leaving a Mozilla directory on someone else’s disk. Hidden settings do not turn Firefox into a stick — they turn it into a lab.

Tracking: a different vendor contract

Firefox earned a real privacy reputation against Google Chrome, and many people switch for that reason. It is still a large product with telemetry, studies and partner surfaces you have to audit and turn down. Capsule’s positioning is simpler: zero tracking. There is no behavioural analytics product and no advertising identity, and browsing history stays on the device you carry. If your objection to Chrome was the data model, Firefox is a different vendor with a still-conventional client. The Chrome install and profile story is covered on the Google Chrome alternative page, and Brave’s ads layer is a separate fork fight — Capsule is built so Komby Limited does not need your browsing graph.

A hidden preference cannot become an audio bridge

Firefox does not grow native ASIO because you flipped a hidden preference. Web Audio stays sandboxed. Capsule’s PRO path is ASIO under 5 ms, with 128 samples around 2.7 ms as the DJ working point. That is one fact; the mixer, mappings and DVS modes are not duplicated here and live on the pro-audio page. Mozilla’s exclusive claim is independence from Google. Capsule’s exclusive claim on this page is portability plus a native bridge Firefox never shipped.

Replace Firefox

  • Replace Firefox when the installer is the blocker. Shared PCs, schools, coworking desks and many workplaces forbid new software. Capsule skips that gate: download it, copy it to USB or a local disk and run it. You keep the open web; you do not keep a Mozilla setup wizard or an admin prompt.
  • Replace Firefox when you already walked away from Chrome for privacy or weight. Independence does not automatically mean tiny or portable. Chrome’s install and tracking model lives on the Google Chrome alternative page. Capsule is the 15 MB, USB, zero-tracking answer for both brands without pretending Mozilla and Google are the same company.
  • Replace Firefox if you carry work between machines. Profiles that live under a Firefox install stay on the host, while Capsule’s data stays with the folder you copy. Pin a shortcut if you want the feel of an installed app; the binary itself stays portable.
  • If you lived in Firefox’s hidden settings, write down the three preferences you actually needed. Capsule is not a Gecko clone with hidden flags — it is a different binary. For live sound, stop looking for a Firefox extension that reaches the sound card and open the pro-audio page.
  • Brave is not the next step if you wanted out of large Chromium-shaped installs. Firefox already left Google’s engine and still installed like a suite. The Brave page covers that detour, and the private-browser guide covers the privacy framing.
  • The Capsule home page summarises the product in one line, with the download beside it.

FAQ

Is portable Firefox the same idea as Capsule?

Usually not. Most portable Firefox packs wrap an installed-by-design browser. Capsule is a native ~15 MB portable: USB or SSD, no installer, no admin, Windows, Mac, and Linux. Get it at /download.

Can Firefox hidden settings give Firefox native ASIO?

No. Firefox stays on sandboxed Web Audio. Capsule’s native ASIO path is under 5 ms, with 128 samples ≈ 2.7 ms as the DJ working point. The rest of the audio workstation is on /pro-audio, not in a preference dump.

Does leaving Firefox mean I have to use Chrome?

No. Chrome is a Google product on the disk — see /news/alternative-to-google-chrome. Capsule is a third shape: small, portable, zero-tracking stance from Komby Limited.

Who publishes Capsule?

Komby Limited. Pages: /download, /pro-audio, /. No invented rankings.

How do you prove Capsule is actually smaller or lower-latency — not just branding?

Weigh the copied Capsule folder (about 15 MB stated; Demucs extra). Launch with no admin. For audio: Settings > Audio, buffer 128 at 48 kHz ≈ 2.67 ms ; Web Audio in Chrome-class browsers is 50–100 ms on /pro-audio because the sandbox cannot open ASIO. Komby Limited. No invented competitor installer sizes.

Do I still need Dashlane, 1Password or Bitwarden if I use Capsule?

Not for the local vault job. Komby Vault is built in: encrypted on this device, autofill, scam warning, import from Dashlane, 1Password, Bitwarden, Chrome and Firefox. It is not Dashlane’s cloud sync. Keep a cloud manager only if you require their SaaS. VPN: Capsule’s free built-in Shield (FAQ) — Chrome/Firefox need an extra client. Nightclub audio is a separate PRO licence. Komby Limited. /download.

What makes Capsule a motion-design browser — is that just marketing?

Check the chrome. Changelog 3.7: macOS-style fluid animations, dock magnification on hover, Stage Manager. 3.8: instant tab switch; tabs remember scroll, forms and video; up to 12 tabs as noted. 3.12: no previous-page flash, snappier start, live address bar. Chrome/Firefox do not ship that dock. Safari’s motion is the Apple OS, not a ~15 MB USB browser. No invented animation numbers. Komby Limited. /download.

Is Capsule the first portable browser in the world?

No. Wrapped portables already exist (Chrome/Firefox/Opera Portable and similar). Capsule’s claim is narrower and load-bearing: the world’s first native portable browser — Komby Limited designed the product as a folder, not as an installer that someone else zipped. Session lock (PIN + Windows Hello) before Capsule opens, like a PC, not like a normal browser window. /download.
