Mozilla never decided an official consumer Firefox Portable — Capsule did
People type “Firefox Portable” because they want to carry the browser on a stick without installing anything. Mozilla does not ship that: official Firefox installs, updates, and leaves a profile on the PC. What circulates under that name are mostly unofficial packs — handy for some technicians, often with an “unofficial” warning. Capsule was designed as a portable browser from the start. Komby Limited ships an about-15 MB folder you copy to USB, with PIN, Windows Hello, and Vault. The question is not which Firefox wrap is better; it is which product was built for the stick.
Why the real question is official intent, not a better wrap
Mozilla’s decision versus Komby Limited’s decision
Official Firefox is an installer, Mozilla-managed updates and a profile on the PC. Mozilla never published “Firefox Portable” as a consumer product. Third parties wrap Firefox into a folder to dodge the installer, which can be useful for a technician but is not Mozilla’s consumer roadmap. Capsule is the opposite story: Komby Limited designed the product as a folder you copy from the start.
A geek workaround versus a product for everyone
Finding an unofficial Firefox Portable sends you down a technical path: packs, warnings and update chores. Most people simply open Firefox from the Start menu. Capsule skips the technical path: download the file, copy about 15 MB and launch it with no admin rights. The USB and no-admin guides cover the usual environments.
Lock, Vault and stick — the portable product
A PIN or Windows Hello gate opens before the first tab. The vault is encrypted on this device. When you unplug the stick, the browser leaves with you. A Firefox wrap is still Firefox, with Mozilla size, Gecko and Web Audio underneath; the private-browser page covers the session-lock vocabulary.
Compare Capsule to installed Firefox
If your real goal is to leave Firefox, the useful page is the Firefox alternative, because Firefox is Mozilla’s product. This page exists because people still type “Firefox Portable” — and the honest answer is that there is no official consumer Mozilla portable, but there is Capsule. The size discussion lives on the 15 MB page, and the pro-audio page explains the audio details.
Carry the official portable
- Download Capsule, copy the folder, set the PIN and clone the stick before the first trip.
- If the real goal is leaving installed Firefox, read the Firefox alternative page. The portable-browser and USB-browser guides cover the folder and the media.
- There is no sense in waiting for Mozilla to ship an official consumer Firefox Portable. Capsule already is the publisher-made portable.
- The Capsule home page gathers everything in one line, with the download beside it.
