Extension Manager

You install extensions once.
You should be able to run them
on demand.

Extension Manager turns the chaos of installed extensions into a small set of profiles you toggle by hand — and a one-key Focus Mode that pauses everything you don’t need right now.

№ 03 — The instrument

Three moves.
That’s the whole product.

Profiles

A profile is a named set of extensions to enable. Activate Reading and your dictionary, reader-mode, and highlighter extensions come on; everything else goes quiet.

Switch profiles in one click from the toolbar popup.
Members are pure references — deleting a profile never uninstalls anything.
Always-on entries stay enabled across all profiles.

Focus Mode

Press ⌃+⇧+F. Every extension outside your always-on list pauses. Press it again to restore the exact state you were in before.

Reversible: Focus snapshots your state, restores on toggle off.
Survives across tabs and windows; it’s a browser-wide flag.
Status is visible at a glance — the toolbar mark glows amber.

The Always-on list

Pin the extensions you can’t live without — password managers, ad blockers, screen readers. Profiles and Focus Mode never disturb them. Set it once, forget it.

Independent from any profile — a global “don’t touch” set.
Pinned extensions show a small always-on badge in the popup.
Empty by default. You opt in deliberately.

Local. Always.
No accounts. No telemetry.
No backend to compromise.

Profiles and lists live in your browser’s chrome.storage.local. They never leave your machine. There is no server. There never will be.

ii.

Extension Manager doesn’t read what your other extensions do, your tabs, or your data. It only asks Chrome to flip them on and off.

iii.

The management permission you grant on install is the strongest one we ask for. We use it for one thing: setEnabled. That’s it.

iv.

One permission, one purpose. The management permission lives in the manifest as optional and is requested at runtime, not on install — so you can see what it’s for before you grant it.

Add it. Toggle a profile. Forget about it.

Extension Manager runs on Chrome and any Chromium-based browser (Edge, Brave, Arc, Vivaldi). Free. Forever. No upgrade tier.

You’ll be asked to grant the management permission. Required to enable and disable other extensions. Nothing else is requested. Nothing else is read.

The browser is the
new operating system,
and your extensions
are processes you
forgot you started.
