Chrome Extensions Not Working? How to Fix Them
Chrome extension stopped working? Enable and pin it, grant site access, allow Incognito, force updates, then disable the others to find the conflict.
When a Chrome extension stops working, the fix is usually quick: confirm it’s actually enabled, give it permission on the page you’re using, and make sure both the extension and Chrome are current. Most breakage traces back to a toggled-off switch, a blocked site permission, or a clash with another add-on. Work through the checks below and you’ll clear most cases in minutes.
Confirm it’s enabled and pinned
Open chrome://extensions, or click the puzzle-piece icon in the toolbar and choose Manage extensions. Make sure the toggle on the extension’s card is on. Then click the puzzle piece and use the pin icon to keep it visible in your toolbar. If a card shows a “This extension may have been corrupted” warning, click the Repair button.
Update the extension, then Chrome
Both update on their own, but forcing it rules out a stale build. On chrome://extensions, turn on Developer mode (top right), then click the Update button to refresh every extension. Next update the browser at Menu > Help > About Google Chrome (or chrome://settings/help) and click Relaunch. If Chrome also keeps closing on you, work through why Chrome keeps crashing before blaming the add-on.
Fix permissions and Incognito access
Many extensions only run where you’ve granted access. Click the extension’s Details button and check Site access: pick On all sites to run everywhere, or On click to trigger it yourself. Extensions are off in private windows by default, so if it fails only there, turn on Allow in Incognito. A cookie- or login-based extension can also right itself after you clear cookies in Chrome.
Isolate a conflict or reinstall
Two extensions fighting over the same page can break both. Disable every extension except your target, confirm it now works on its own, then re-enable the rest one at a time until it breaks again; the last one switched on is the culprit. Still dead? Remove it and reinstall from the Chrome Web Store. On a managed work or school computer, an administrator can block add-ons - a blocked extension shows a notice directly on its card in chrome://extensions.
| Check | Where | What to do |
|---|---|---|
| Enabled | chrome://extensions | Switch the card’s toggle on |
| Pinned | Puzzle-piece icon | Click the pin to keep it visible |
| Updated | Developer mode > Update | Force the newest version |
| Site access | Extension Details | Set On all sites or On click |
| Incognito | Extension Details | Turn on Allow in Incognito |
| Conflict | chrome://extensions | Disable others, re-enable one by one |
Run these top to bottom and stop as soon as the extension works again. If several act up at once, the browser is the likelier cause, and a Chrome that feels slow overall is worth cleaning up first.
