Permission rationale

Permission	Why it's needed
storage	Saves the single on/off preference (reelScrollerEnabled) locally in Firefox extension storage. Nothing is synced or sent remotely.
tabs	Lets the background script enumerate open Instagram tabs and send ENABLE/DISABLE messages when the toolbar button is clicked.
activeTab	Allows interaction with the currently focused tab when the toolbar button is pressed.
*://instagram.com/* *://*.instagram.com/*	Scopes content script injection to Instagram URLs only. No other domains are ever accessed.

Notable manifest settings

• "persistent": false — The background script is non-persistent. Firefox can unload it when idle, reducing memory usage.
• "run_at": "document_idle" — The content script is injected after the page has finished loading, so the DOM is ready.
• "data_collection_permissions": { "required": ["none"] } — Explicitly declares that the extension collects no data, as required by Firefox's manifest policy for extensions that collect no user data.
• "strict_min_version": "140.0" — Minimum supported Firefox desktop version. Android requires 142.0.
