Mouse Jiggler — Stay Online & Active Chrome extension security report

Mouse Jiggler keeps your screen awake and your browser session looking active, from a single toggle in your Chrome toolbar. Click once and it holds the display on and quietly sends activity into the tab you are working in, so the screen saver never appears and web apps do not decide you have wandered off. Built for the long stretches where you are at your desk but not touching the keyboard: reading a long document, watching a build finish, presenting to a room, keeping an eye on a dashboard. 🖱️ Read this first — what a browser extension can and cannot do Being straight with you matters more than a bigger feature list. A Chrome extension runs inside the browser and cannot move your operating system's mouse pointer, and no extension that claims otherwise can either. Here is exactly what this one does: ✅ Keeps your display awake, so the screen never sleeps and the lock screen stays away ✅ Sends movement activity into the tabs you switch it on for, so their own idle timers keep resetting ✅ Works on any site you choose, with no permissions requested at install time ❌ Does not move the physical mouse cursor on your desktop ❌ Does not touch applications outside Chrome If you need the real pointer to move across your whole desktop, you need a hardware jiggler or a desktop app — not a browser extension. ⚡ What This Mouse Jiggler Does ➡️ One big toggle — on or off, no configuration needed to get going ➡️ Keep-awake holds the display on using Chrome's power API, so no screen saver and no lock screen ➡️ Activity simulation sends a movement event into your tab on a schedule you choose ➡️ Pick the interval: every 15 seconds, 30 seconds, 1 minute or 2 minutes ➡️ Auto-off timer stops everything after 30 minutes, 1, 2, 4 or 8 hours so it never runs all night ➡️ Live session timer shows how long it has been running ➡️ ON badge on the toolbar icon, so you always know its state at a glance ➡️ Optional per-site memory: allow a site once and it resumes there by itself after a reload ➡️ Dark mode and light mode, remembered between sessions 🔐 Why the Permissions Are So Small Most extensions in this category ask to read and change your data on every website you visit, the moment you install them. This one does not. ➡️ Nothing is requested at install beyond storage and the ability to act on the tab you are looking at ➡️ When you switch it on, it acts only on the tab in front of you, because you clicked ➡️ If you want it to survive reloads on a particular site, you grant that one site yourself from the popup, and you can revoke it any time in Chrome's settings ➡️ It never asks for access to all your sites, and it cannot read the pages you visit 👥 Who Finds This Useful 1️⃣ Anyone reading a long report or watching a video who is tired of the screen dimming every two minutes 2️⃣ People presenting or screen-sharing who cannot risk the lock screen appearing mid-demo 3️⃣ Developers watching a long build, deploy or test suite finish 4️⃣ Anyone monitoring a live dashboard, log stream or status board on a second screen 5️⃣ Support and ops staff who need a web tool to stay logged in during a quiet shift 6️⃣ People on a call in a browser-based meeting tool who are listening rather than typing 7️⃣ Anyone whose web app logs them out or marks them away after a few idle minutes 8️⃣ Anyone who keeps nudging the mouse every couple of minutes out of habit ✨ Why People Like It 🔹 One click to start — no setup, no account, no sign-in 🔹 Keep-awake and activity in a single switch, instead of two separate extensions 🔹 Honest about what it does, so nothing behaves unexpectedly 🔹 The auto-off timer means you can turn it on and forget about it safely 🔹 A clean, quiet interface with a clear Active or Inactive state 🔹 Deliberately minimal permissions, so installing it is a small decision 🔹 Completely offline — no servers, no analytics, no tracking 🔹 Light and dark themes ⚙️ Features In Detail ⭐ Master toggle with a live status ring and a session timer ⭐ Keep screen awake, which also stops the system idling into sleep ⭐ Configurable activity interval, so you can match your app's idle timeout ⭐ Auto-off after a set time, with the countdown handled reliably by Chrome's alarms ⭐ Per-tab status card that tells you whether activity is running on the page in front of you ⭐ One-click permanent access for a site you use every day, entirely optional ⭐ Toolbar badge showing ON while a session is running ⭐ Clear explanation in the popup of what is and is not possible 🔧 Behind-the-Scenes Tech (Explained Simply) 🎯 Keep-awake uses chrome.power, the API Chrome provides for exactly this purpose 🎯 Activity simulation dispatches pointer movement events into the page, and nothing else — no clicks and no key presses, so it can never trigger a shortcut or type into a form by accident 🎯 Auto-off uses chrome.alarms rather than a timer, so it still fires reliably after Chrome idles the extension 🎯 Settings are stored with chrome.storage.local and never leave your device 🎯 Manifest V3 — the current Chrome extension standard, secure and up to date 💡 Helpful Tips ✅ Pin the extension so the toggle and its ON badge are always visible ✅ Leave keep-awake on: it is the part that works everywhere, including Chrome's own pages ✅ Shorten the interval to 15 seconds if an app still marks you away ✅ Set an auto-off time that matches your working block, so it never runs overnight ✅ Use it on the tab that matters — switching it on acts on the tab you are looking at ✅ For a site you use every day, use the always-keep-active button once and stop re-arming it ✅ Reloading a page clears the activity loop unless you granted that site; the popup will tell you and offer one click to restore it ❓ FAQ ► Does this move my actual mouse cursor? No. No Chrome extension can move the operating system's pointer. It keeps the display awake and simulates activity inside browser tabs. For real cursor movement you need a hardware device or a desktop application. ► Will it stop my screen locking? It stops the display sleeping while it is on, which prevents the screen saver and the lock screen in normal setups. A policy on a managed work device can still force a lock, and the extension cannot override that. ► Does it need access to all my websites? No. It asks for nothing at install. Switching it on acts on the tab you are looking at because you clicked. Granting a specific site permanent access is optional and entirely your choice. ► Do I need an account? No. There is no sign-in, no registration and no subscription wall. ► Does it work when Chrome is minimised? Keep-awake keeps working. Activity simulation keeps running in the tab as long as Chrome is running and the tab is open. ► Why did it stop after I reloaded the page? The activity loop lives in the page, so a reload clears it. Either switch it on again from the popup, or grant that site permanent access so it restarts by itself. ► Can I use it on Chrome system pages? Activity cannot be simulated on chrome:// pages or the Web Store — no extension is allowed to touch those. Keep-awake still works there. ► Does it send my data anywhere? No. There are no network requests, no analytics and no accounts. Your settings stay in local storage on your device. 🚀 How to Get Started 1️⃣ Install the extension and pin Mouse Jiggler to your toolbar 2️⃣ Open the tab you want to stay active in 3️⃣ Click the icon and press the big power button — the badge turns ON 4️⃣ Pick an interval and an auto-off time that suit your session 5️⃣ For a site you use daily, tap the always-keep-active button once 6️⃣ Press the button again when you are done, or let the auto-off timer handle it That is it — one toggle that keeps your screen on and your session active, with permissions small enough that installing it is an easy decision. Hope it saves you a few hundred pointless mouse nudges! 🙌
