Where to find and re-enable a disabled extension
When a Chrome extension stops working, it is usually because you or Chrome itself turned it off. The extension is still installed — it is just inactive. You can turn it back on in about 30 seconds by going to your extensions list and flipping the toggle.
Open Chrome and click the puzzle-piece icon in the top right corner of your browser window. If you do not see it, click the three vertical dots (the menu button) instead, then look for "Extensions" in the dropdown. Either way, you will see a list of your installed extensions with a toggle switch next to each one. Find the extension you want to use, and click its toggle to turn it back on. The toggle will change color — usually from gray to blue — and the extension is now active again.
If you cannot find the extension in that list, it may have been uninstalled rather than disabled. In that case, you would need to reinstall it from the Chrome Web Store, but that is a different process than re-enabling.
Key Takeaways
- A disabled extension is still installed but inactive — you turn it back on with a toggle switch, not by reinstalling it.
- The extensions list is accessed through the puzzle-piece icon in the top right, or through the menu button if the icon is not visible.
- Chrome sometimes disables extensions automatically if they have not been updated or if they conflict with your security settings.
- Once you re-enable an extension, it will stay on unless you or Chrome disables it again for a specific reason.
Why Chrome disables extensions on its own
Chrome will automatically turn off an extension if it has not been updated in a long time, or if the developer stopped maintaining it. This is a security measure — old extensions can have bugs or vulnerabilities that newer versions of Chrome no longer support. When this happens, you will usually see a message in the extensions list explaining why it was disabled.
You can re-enable an outdated extension by clicking its toggle, but Chrome may disable it again if the developer does not release an update. If you rely on that extension, check the Chrome Web Store to see if the developer has posted an update, or look for a similar extension that is actively maintained.
Re-enabling an extension that Chrome flagged as suspicious
Occasionally Chrome disables an extension because it detected behavior that looked suspicious — for example, if the extension tried to access data it should not need, or if Chrome's security systems flagged it as potentially harmful. In this case, the toggle will be off and you may see a warning message.
Before you re-enable it, read the warning carefully. If you installed the extension yourself from the official Chrome Web Store and you trust it, you can click the toggle to turn it back on. If you are not sure where it came from or what it does, it is safer to leave it disabled and uninstall it instead. You can always reinstall a legitimate extension later if you change your mind.
What to do if the toggle does not work
If you click the toggle and nothing happens, or if the extension turns back off when ready, there is usually a conflict or a permissions issue. First, try closing Chrome completely and opening it again — sometimes a restart fixes the problem.
If that does not work, go back to the extensions list and look for any error messages or warnings next to the extension's name. Chrome will sometimes display text like "Remove extension" or "This extension is not available" — these messages tell you whether the extension can be re-enabled or whether you need to uninstall and reinstall it. If you see no message and the toggle still will not stay on, uninstall the extension and reinstall it fresh from the Chrome Web Store.
Turning off extensions you do not use
You do not have to uninstall an extension to stop using it — you can straightforward turn it off by clicking its toggle. This keeps the extension installed so you can turn it back on later without having to find it in the Web Store again. Turning off extensions you rarely use can also make Chrome run slightly faster, since inactive extensions use less memory.
If you have many extensions and want to clean up your list, you can disable the ones you do not need regularly and keep only the ones you use every day turned on. You can always re-enable them whenever you want.
Managing extension permissions after re-enabling
When you re-enable an extension, it will have the same permissions it had before — meaning it can access the same websites and data it could access when it was on. If you want to limit what an extension can do, you can change its permissions without disabling it entirely.
Click the extension's name in the extensions list to open its details page. Look for a "Permissions" or "Site access" section. From there, you can choose whether the extension can run on all websites, only on specific sites, or only when you click it. These settings stay in place even if you turn the extension off and back on again.
Frequently Asked Questions
Why did Chrome disable my extension without asking me?
Chrome automatically disables extensions that are very old, no longer maintained by their developer, or flagged as potentially unsafe. This happens in the background to protect your security. You can re-enable it by clicking the toggle, but Chrome may disable it again if the developer does not release an update.
Will re-enabling an extension slow down Chrome?
Most extensions have a small impact on Chrome's speed, but it is usually not noticeable unless you have many extensions running at once. If Chrome feels slow, try disabling extensions you do not use regularly rather than uninstalling them — that way you can turn them back on later if you need them.
Can I re-enable an extension that I accidentally uninstalled?
If you uninstalled an extension completely, you will need to reinstall it from the Chrome Web Store — you cannot re-enable it from the extensions list. Search for the extension by name in the Web Store and click the "Add to Chrome" button to install it again.
What if an extension keeps getting disabled automatically?
If Chrome keeps disabling the same extension even after you turn it back on, the developer likely stopped updating it and Chrome considers it unsafe. Check the Chrome Web Store to see if a newer version is available, or look for a similar extension that is actively maintained by its developer.
