Z-Manager groups the extensions you already have into profiles — Work, Dev, Shopping, Minimal — and flips between them in a single click. Everything stays inside your browser.

Three packages, one honest status each

Chrome and Firefox both refuse one-click installs from outside their stores. Rather than hide that, every option below states exactly what it does and what it needs from you.

Chrome logo

Chrome

Chrome · Edge · Brave · Arc · Opera

ReadyZIP · v1.2.0

The full build: profiles, bulk actions, permission audit. Chrome blocks raw .crx installs from outside the Web Store, so it loads as an unpacked folder in developer mode.

  1. 01Download and unzip the package
  2. 02Paste chrome://extensions in the address bar
  3. 03Turn on Developer mode, top right
  4. 04Click Load unpacked and pick the folder
Firefox logo

Firefox

Developer Edition · Nightly

Awaiting AMO signatureXPI · v1.2.0

The read-only Firefox build: inventory, details and permission audit. Toggling is disabled because Firefox restricts management.setEnabled to themes. Release Firefox installs signed add-ons only.

  1. 01Download the .xpi package
  2. 02Open about:debugging → This Firefox
  3. 03Choose Load Temporary Add-on
  4. 04Release channel needs the AMO-signed build
Enterprise CRX logo

Enterprise CRX

Managed Chrome devices only

Policy readyBUNDLE · v1.2.0

A managed-deployment bundle containing the signed CRX3, update manifest, exact extension ID, policy templates and platform instructions. It is not a drag-and-drop installer for unmanaged Chrome.

  1. 01Download and unzip the enterprise bundle
  2. 02Host the CRX and update XML at the listed URLs
  3. 03Deploy one included policy through device management
  4. 04Verify chrome://policy before installation

Built for the shelf you already have

Group, search, audit, switch

  • 01

    Profiles that actually switch

    Build a group once, then activate it. Members turn on, everything outside the group turns off. Additive mode leaves the rest alone when you only want to add tools.

  • 02

    A popup built for the keyboard

    Focus lands in the search field. Digits activate groups, arrows walk the list, space toggles. The mouse is optional.

  • 03

    Search and filter the whole shelf

    Fuzzy search by name, then filter by enabled, disabled, sideloaded, or by a permission you care about.

  • 04

    Bulk actions without the dread

    Enable all, disable all, disable all-but-this, invert the selection. Policy-installed extensions are shown as locked rather than silently skipped.

  • 05

    Permission audit per extension

    Real permission warnings and host access straight from the browser, plus install provenance: store, sideloaded, developer or enterprise policy.

  • 06

    Details and deep links

    Version, ID, description, options page, homepage and store listing. One click into the browser's own details page when you need the native controls.

Honest limits

What no extension manager can do

Browsers deliberately sandbox extensions from one another. Any tool that claims these features is guessing, or shipping a native helper you did not ask for.

  • No per-extension CPU or RAM

    Chrome shows this only in its internal task manager. There is no public API for it, in any browser. We would rather show nothing than invent a number.

  • No usage tracking of other extensions

    One extension cannot observe another's clicks, network calls or storage. "Unused for 30 days" is always a guess, so we do not dress it up as data.

  • No native grouping

    Browsers have no concept of an extension group. Groups are Z-Manager's own metadata plus scripted toggling — which is exactly why they are portable.

  • No copying another extension's files

    Nothing can read the folder an installed extension lives in. Backups come from the Web Store package service, which is why sideloaded and development items export metadata only.

  • No off-store one-click install

    Chrome refuses off-store packages, so the ZIP needs developer mode. Firefox add-ons must be signed by Mozilla to run on release builds.

Release history · current v1.2.0

Every packaged release, newest first. Expand an entry to see exactly what changed in the extension and on this site.

v1.2.02026-08-27Current
  • Back any installed extension up to your PC as a CRX or ZIP package.
  • New backup engine: store-published extensions are pulled from the Chrome Web Store package service and saved with their real name, version and ID in the filename
  • Choose CRX (verbatim signed package) or ZIP (the same package with the signature header stripped, ready to unpack)
  • Popup rows gained a download action with a format picker; the dashboard gained a Backup section with filters, multi-select and a live progress log
  • Sideloaded, development and policy extensions export a metadata JSON instead — no browser exposes their package to another extension
  • Full snapshot export bundles profiles, aliases, preferences and the whole inventory with permission warnings into one file
v1.1.12026-08-26Previous
  • Replaced the misleading raw CRX flow with a complete enterprise deployment bundle.
  • Managed CRX now carries a stable self-hosted update URL while the unpacked Chrome ZIP stays unchanged
  • Generated update XML, ExtensionSettings and ExtensionInstallForcelist policy templates all share the verified extension ID
  • Enterprise bundle includes the CRX, update manifest, policy files and Windows, macOS and Linux deployment guidance
  • Download copy now states that unmanaged Chrome rejects off-store CRX drag-installs with CRX_REQUIRED_PROOF_MISSING
v1.1.02026-08-26Earlier
  • Redesigned popup, admin-style dashboard, CRX package and in-browser previews.
  • Popup rebuilt: icon-led row actions, tactile search field with keycap hints, segmented filters and larger app tiles
  • Inter and JetBrains Mono bundled locally as woff2, so typography survives the extension CSP
