When auto refresh stops working, the cause is almost always one of a handful of predictable issues. This guide walks through every common problem with specific diagnostic steps and fixes.
Problem: Auto Refresh Stopped Working
Timer shows stopped or inactive
If you set up auto refresh and come back to find the tab hasn't refreshed:
Common causes for timers stopping unexpectedly:
- Chrome tab suspension: Chrome automatically suspends tabs that haven't been interacted with to save memory. Suspended tabs stop executing JavaScript, which pauses the refresh timer. Keep the tab visible or use a tab-freezing prevention extension.
- Chrome updates: Background Chrome updates can interrupt extension processes. After any Chrome update, verify your active refresh tabs are still running.
- System sleep/hibernate: Hibernating or sleeping the computer pauses all JavaScript execution. After waking, timers typically resume but may have missed intervals.
- Extension crash: Extensions can crash without visible error. Check
chrome://extensions— if the extension shows an error badge, click it to see the error, then reload the extension.
Extension icon is grayed out
A grayed-out extension icon on a specific tab means the extension can't operate on that page:
| Page Type | Why Extension Is Grayed Out | Solution |
|---|---|---|
chrome:// pages |
Chrome security restriction — no extensions on internal pages | Cannot be bypassed |
| Chrome Web Store | Chrome blocks extensions on the store | Cannot be bypassed |
file:// URLs |
Extensions require explicit file access permission | Go to chrome://extensions → Auto Refresh Ultra → toggle "Allow access to file URLs" |
| New tab page | New tab page has restricted access | Navigate to any regular website first, then set up refresh |
| PDF viewer | Chrome's built-in PDF viewer restricts extensions | Cannot run auto refresh on PDF tabs |
Auto Refresh Ultra — Reliable Page Monitoring
When configured correctly, Auto Refresh Ultra runs in the background without interruption. Free to install.
Add Auto Refresh Ultra FreeProblem: Page Refreshes But Shows Stale Content
The timer is running and the tab reloads, but the content you're monitoring doesn't update even though you know the page has changed:
Browser cache serving old content
A regular page refresh (F5) asks the server for the page but respects cache headers. If the server says "this content is fresh for 10 minutes," Chrome serves the cached version for 10 minutes regardless of how many times you refresh.
Ctrl+Shift+R — bypassing the cache and requesting a fresh version from the server every time. This is slightly slower (requires a full server round-trip) but guarantees you're seeing current content.
Page content loaded dynamically after page load
Some modern web applications use a shell HTML page that always looks the same, with actual content loaded via JavaScript API calls after the page loads. When you refresh such a page:
- The static HTML shell loads (looks the same as before)
- JavaScript runs and fetches fresh data from the API
- The content area updates (may take 1-3 seconds after the "page loaded" event)
If you're using change detection and it's comparing the page immediately after the load event, it may not capture the dynamically loaded content. The page HTML itself is identical; the visible content changed via JavaScript DOM manipulation after load.
For sites with dynamic content loading, try:
- Increasing the change detection delay — allow 2-5 seconds after page load before comparing content
- Targeting a specific element for change detection rather than the full page
- Checking if the site offers an RSS feed or API you can monitor more directly
CDN-cached content
Content Delivery Networks (CDNs) like Cloudflare, Fastly, or AWS CloudFront cache pages at edge servers. If the origin content changes but the CDN hasn't invalidated its cache, you'll see stale content regardless of how you refresh. Signs you're hitting CDN cache:
- Content is slow to update even when you know the source changed
- Different browsers or incognito mode shows different (newer) content than your regular Chrome session
- Using a VPN to a different location shows different content
CDN caching isn't something Auto Refresh Ultra can bypass — the CDN is returning stale content before it reaches your browser. The site's caching configuration determines how quickly new content propagates.
Problem: Notifications Not Firing
Change detection is enabled, the page is refreshing, but no alert appears when the content changes:
Chrome notification permission
chrome://settings/content/notifications. Scroll to find Auto Refresh Ultra or the extension's notification origin. If it's blocked, change it to allowed. If it's not listed, the extension hasn't requested permission yet — click the extension icon, enable change detection, and Chrome should prompt for notification permission at that point. Grant it.
Operating system notification settings
Chrome notifications flow through the operating system notification system. If Chrome's OS notifications are disabled:
- Windows: Settings → System → Notifications → scroll to find Google Chrome → turn notifications on
- macOS: System Settings → Notifications → Google Chrome → Allow Notifications
- Linux: Depends on desktop environment — check notification daemon settings
Do Not Disturb mode
Windows Focus Assist, macOS Do Not Disturb, and similar features suppress all notifications including Chrome extension alerts. If auto refresh alerts fired previously but suddenly stopped, check if Focus Assist or Do Not Disturb activated.
Change detection sensitivity
If sensitivity is set too high (only detect large changes), small updates — like a single number changing in a price or count — may not trigger the alert threshold. Try setting sensitivity to its minimum (detect any change) to confirm change detection is working at all. Once you confirm it fires, gradually increase sensitivity to filter out trivial changes.
Reliable Change Detection Alerts
Auto Refresh Ultra fires alerts when page content changes — so you're notified the moment something matters.
Get Auto Refresh Ultra FreeProblem: Auto Refresh Causes Login Timeouts
The page requires login, and refreshing repeatedly causes the session to expire and redirect to a login screen:
What's happening
Some applications treat page refreshes as new session events. Authentication tokens or CSRF tokens embedded in the page may expire or conflict when the page is reloaded without an active user interaction. This is a site-level session management decision, not an Auto Refresh Ultra issue.
Workarounds
- Increase the refresh interval — longer intervals give more time between refreshes, reducing token conflict frequency. Start with 5-10 minutes to see if the session holds longer.
- Check "Remember me" / persistent login options — if the site offers persistent authentication, enabling it may make sessions resilient to page refreshes.
- Monitor the pre-login page instead — if the data you need is visible on a public-facing page (e.g., a status page that requires no login), monitor that instead.
- Use a direct URL with parameters — some internal pages can be accessed via bookmark URLs that include session tokens; these may behave differently on refresh.
Problem: Auto Refresh Is Too Slow or Too Fast
Minimum interval limits
The free version of Auto Refresh Ultra has a minimum refresh interval limit. If you need intervals below 30 seconds, upgrading to Pro removes this restriction. For most use cases (tracking changes on live pages), intervals above 30 seconds are both sufficient and more considerate of server load.
Performance impact at short intervals
Very short refresh intervals (5-15 seconds) on content-heavy pages consume significant CPU and memory, particularly when multiple tabs are refreshing simultaneously. If you notice Chrome slowing down during active monitoring sessions:
- Increase intervals where possible — if the data updates every few minutes, 30-second refresh gives you equivalent freshness at 1/4 the resource cost
- Close other unused tabs in the same window
- Use change detection — the page still reloads but you don't need to process the output manually
- Stagger tab refresh intervals to avoid simultaneous refreshes (e.g., Tab 1: 60s, Tab 2: 65s, Tab 3: 70s)

After reinstalling Chrome or creating a new Chrome profile, Auto Refresh Ultra and its settings are gone:

Install Auto Refresh UltraFrequently Asked Questions
Why did auto refresh stop working after Chrome updated?
Chrome updates can interrupt extension timers. After an update, open Auto Refresh Ultra on each monitored tab and check if the timer is still running. If it stopped, toggle it off and back on to restart. For persistent issues after major updates, go to chrome://extensions and reload Auto Refresh Ultra using the refresh icon. Rarely, removing and reinstalling the extension clears corrupted state from the update.
Why does auto refresh work on some sites but not others?
Site-specific factors that prevent auto refresh: login sessions that expire on reload, WebSocket-based real-time pages that don't need refreshing, bot detection that triggers on repeated requests, single-page applications where the URL doesn't reflect the current view, and CDN or server caching that returns stale content. Each requires a specific workaround — increase intervals, target the pre-login page, or recognize that the page uses real-time updates instead of page loads.
Why aren't auto refresh alerts (notifications) firing?
Check three things: (1) Chrome notification permission at chrome://settings/content/notifications — Auto Refresh Ultra must be allowed; (2) OS notification settings — Chrome notifications flow through Windows/macOS notification systems and require those to be enabled for Chrome; (3) Focus Assist or Do Not Disturb mode — system-level notification suppression silences all Chrome alerts. If all three are correct, try setting change detection sensitivity to its lowest setting to confirm the mechanism works at all.
Does auto refresh stop when Chrome goes to sleep or the computer hibernates?
Yes — hibernation pauses all JavaScript execution, which pauses refresh timers. After waking, timers typically resume within 30-60 seconds. For critical monitoring that can't afford missed refreshes, keep the computer running with sleep disabled, and keep the monitored tab as the active visible tab to prevent Chrome from suspending it.
Why does the page refresh but the content looks the same even though I know it changed?
The browser is loading a cached version. Enable force/hard refresh mode in Auto Refresh Ultra to bypass cache and always fetch fresh content from the server. Alternatively, the page may load dynamic content via JavaScript after the initial page load — in this case, change detection should wait a few seconds after the page load event before comparing content.
Can I use auto refresh on Chrome extensions pages like chrome://extensions?
No — Chrome's security model prohibits extensions from operating on chrome:// pages, the Chrome Web Store, and by default on file:// URLs. For file:// access, go to chrome://extensions, find Auto Refresh Ultra, and enable "Allow access to file URLs." The restriction on chrome:// pages and the Web Store cannot be bypassed.
