Every enabled add-on used to be activated synchronously in initAddons(), during app.whenReady and before the window exists. That is the largest launch cost left (boot tracer, 2026-10-03). An add-on can now say "activation": "on-demand" in addon.json. It is then listed at launch but not started. Its declared surfaces stay live: "panels" (new: sidebar panels declared up front), toolbar-menu, context-menu-items and the page-inject bridge, whose source is read on the first matching page. activate() runs on first real use: a panel opened, a menu or context item picked, a message from its panel, tab or page bridge, a Settings addon-invoke, a wiz:// link (for Aegis). All of those go through AddonHost.dispatch(), which starts the add-on and waits for it, so no call is dropped. Concurrent callers share one activation, and activations run one at a time. Startup stays the default: the host cannot tell what an older add-on does in activate(). request-filter add-ons and add-ons that declare no surface are forced to startup. If activate() returns a promise, calls wait for it (at most 5 s). api.startAtLaunch(bool) lets an on-demand add-on ask to be started at launch again (for live relay sessions). Converted: notepad, screenshot, translate, docx-editor, pdf-editor, vpn (none has launch-time work: no file association, no auto-connect, and add-on file tabs are not part of the saved session). Shield and Cookie Pop-ups stay startup: Shield owns the request filter and must see the first request; Cookie Pop-ups costs ~6 ms and acts unasked on every page. Aegis stays startup and untouched: another session owns it. See NOTE-aegis-on-demand.md (next commit). Settings › Performance › Startup: - "Start extensions when first used" (default on). Off = all at launch; switching it off starts the waiting add-ons immediately. - "Start the wallet at launch". Shown disabled with a hint until the installed Aegis manifest allows on-demand. It applies with no Settings change once Aegis opts in. - "Preload common menus" gates prewarmOverlays(). - "Use lightest" preset. New keys are plain SETTINGS_DEFAULTS through the existing settings-set. No new IPC channels. Measured: boot-trace, fresh profile, --seconds 20 so the 30 s add-on OTA poll can't swap Aegis mid-series; warm runs 2-3 of two paired series. - Add-on activation at launch: 121-154 ms -> 104-174 ms. The six converted add-ons went from 16-20 ms to 0. The rest is Shield (83-148 ms, noisy) and Aegis (15 ms in this tree's 0.9.0). - Toolbar painted: 1278-1584 ms -> 1282-1481 ms (within noise). - With "Preload common menus" off: 0 overlays prewarmed, 8 processes instead of 11, about 50-70 MB less at 15 s. The bundled add-on versions are not bumped. Existing profiles keep their old addon.json, and so stay on startup activation, until those add-ons ship with a higher version (seedBundledAddons only reseeds a strictly newer bundle).
