Chrome, Microsoft Edge and Firefox all include their own add-on managers on Windows, so routine extension work does not require a separate manager program. From each browser’s built-in page you can enable, disable, configure or remove extensions, review permissions and, in Chrome, repair a damaged installation.
The instructions below cover Windows 10 and Windows 11. Use the section for your browser, then follow the security and troubleshooting guidance if an add-on behaves unexpectedly.

Browser add-on management at a glance
| Browser | Open the manager | Permission and access controls | Install and recovery notes | Administrator controls |
|---|---|---|---|---|
| Google Chrome | More (⋮) > Extensions > Manage extensions | For each extension, Details lets you allow access on all sites, selected sites or no sites, and allow or deny incognito use. | Install from the Chrome Web Store. A corrupted extension has a Repair option; persistent corruption calls for reputable antivirus or anti-malware scanning. | Not specified in the cited Chrome help page. |
| Microsoft Edge | Extensions (puzzle-piece icon) > Manage extensions | Requested permissions are shown during installation. The cited support page does not specify a per-site access control comparable to Chrome’s. | Use Microsoft Edge Add-ons, or allow extensions from other stores before installing a compatible Chrome Web Store extension. | On managed devices, allowlists, blocklists, force-install policies and policies that stop users re-enabling a disabled extension are available. |
| Mozilla Firefox | Extensions button > Manage extensions | The Add-ons Manager provides extension settings; the cited help page does not state a specific all-sites or selected-sites permission control. | Use Mozilla Add-ons and manage each installed extension from the Add-ons Manager. A separate repair procedure is not stated in the cited help page. | Administrator controls are not described in the cited Firefox help page. |
These differences matter when you are limiting an extension’s access, installing one from another store or using a work or school computer. The detailed procedures explain exactly what to select.

Manage extensions in Google Chrome
Open Chrome’s extension manager
- Open Chrome on Windows.
- Select More (⋮) in the upper-right corner.
- Choose Extensions, then Manage extensions.
The resulting page lists every installed extension and puts its main on/off switch beside it. This is Chrome’s normal control center; you do not need a second Windows application.
#1 Best Overall
Turn an extension on or off
Use the switch on an extension’s card. Turning it off stops the extension from running while leaving its files and settings installed, which is useful for troubleshooting or a temporary privacy change. Turn it back on from the same page when you need it again.
Limit site access and incognito use
- Select Details on the extension you want to review.
- Under site access, choose whether it can read and change data on all sites, specific sites or no sites.
- Decide whether to allow the extension in incognito windows. Incognito permission is controlled separately, so an extension can be disabled there even while it remains active in ordinary windows.
Grant the narrowest access that still supports the extension’s purpose. An extension that only works on one web application normally does not need access to every website you visit.
Repair a corrupted extension
- Return to More (⋮) > Extensions > Manage extensions.
- Find the affected extension and select Repair.
- Confirm the repair when Chrome asks.
Repair reinstalls or refreshes the extension without requiring you to search for a replacement manually. If it remains corrupted, Google warns that another program may be changing the extension’s files: “If you repaired an extension but it’s still corrupted, a suspicious program might be changing this extension’s files.” Run reputable, up-to-date antivirus or anti-malware software on Windows and remove any unwanted program it identifies. The full Chrome procedure and warning are documented in Google’s Chrome extension help (accessed 17 October 2026).
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Remove an extension completely
You can uninstall from either of two places:
- Select the extension’s toolbar icon, then choose Remove from Chrome.
- On Manage extensions, select Remove on the extension’s card and confirm.
Removal deletes the extension from Chrome rather than merely stopping it. If you might need it later, switch it off first and check whether the browser problem disappears.
Recognize Chrome-installed software and trust warnings
Chrome notes that an application installed on Windows or macOS can install an extension. If an unfamiliar extension appears after installing another program, investigate that program instead of assuming the extension was added intentionally. Chrome’s enhanced protection can also warn when an extension is not trusted; treat that warning as a reason to verify the publisher and requested access before enabling it.
Manage extensions in Microsoft Edge
Open Edge’s extension manager
- Open Edge on Windows 10 or Windows 11.
- Select the Extensions button beside the address bar. It uses a puzzle-piece icon.
- Choose Manage extensions.
The management page shows installed extensions and a switch for each one. Microsoft describes extensions as tools that customize the browser and give you more control over browsing; the built-in page is where you exercise that control.
Install an Edge extension safely
- From the extension manager, select Get Extensions for Microsoft Edge.
- Open the listing for the extension you want and read the permissions it requests.
- Select Add extension only after the permissions and publisher make sense for the feature.
Edge can also run compatible extensions from the Chrome Web Store. To use that source, first allow extensions from other stores when Edge presents the option, then review the Chrome listing’s permissions before selecting its add command. Installing from an official store reduces the chance of receiving a modified package, but it does not eliminate the need to inspect access requests.

Disable or remove an Edge extension
On Manage extensions, switch an extension off to stop it running while keeping it installed. To uninstall it, use the extension icon’s context menu and choose the remove command, or use the remove control on its card in the management page. Removing is appropriate when an extension is unwanted, changes browser behavior or continues causing problems after being disabled.
Understand Edge policies on work or school computers
An administrator can control Edge extensions centrally. Microsoft documents an ExtensionInstallBlocklist to block extensions, an ExtensionInstallAllowlist to permit only approved extensions, force-installed extensions that users cannot choose to install themselves, and policies that disable an extension while preventing users from re-enabling it. These controls explain why a remove button may be unavailable or why an extension returns after you turn it off. Policy details are published in Microsoft’s Edge extension-management documentation.
Manage add-ons in Mozilla Firefox
Open the Add-ons Manager
- Open Firefox.
- Select the Extensions button on the toolbar.
- Choose Manage extensions at the bottom of the panel.
This opens Firefox’s Add-ons Manager. Mozilla states that the manager lets you view, enable, disable, remove and manage all installed extensions. Its official instructions are available in the Firefox Extensions button guide (accessed 17 October 2026).
Enable, disable or configure an extension
Find the extension in the Add-ons Manager and use its enable or disable control. Open the extension’s settings to adjust the options supplied by its developer. Disabling is reversible and is a good first diagnostic step when pages load incorrectly, the toolbar changes or Firefox becomes slow.
Remove an unwanted extension
Use the remove control on the extension’s entry in the Add-ons Manager and confirm. If you only want to hide an icon, do not uninstall: pinned extension icons can be rearranged on the Firefox toolbar while the extension remains installed.
Permissions, privacy and safe installation
Read the requested access before installing
An extension may need to read or change website data, access browsing-related information or run in private windows. Match each request to the feature you expect. A simple page-theme tool asking to read data on every site deserves more scrutiny than a tool whose stated purpose requires that access.
- Prefer the official Chrome Web Store, Microsoft Edge Add-ons or Mozilla Add-ons directories.
- Check the publisher name, description and update history before installing.
- Do not enable incognito or private-window access unless you specifically need the extension there.
- Revisit permissions after major extension updates; capabilities can change when an extension is updated.
React to unexpected browser changes
If an extension changes your search engine, home page, new-tab page or other browser settings without a clear reason, switch it off immediately. If the change stops, remove the extension and review recently installed Windows applications as well. Re-enable it only after confirming that the behavior was expected and the requested permissions are appropriate.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Troubleshoot extensions that will not behave
Use a controlled disable test
- Disable the suspected extension in the browser’s manager.
- Close and reopen the affected browser window.
- Repeat the task that previously failed.
If the issue disappears, re-enable extensions one at a time until the cause is identified. This avoids deleting several extensions when only one is responsible.
When Chrome repair does not work
Use Chrome’s Repair command first. If corruption returns or the repair fails, scan Windows with reputable antivirus or anti-malware software because suspicious software may be modifying extension files. Remove detected unwanted software, restart Windows and check the extension manager again.
When Edge will not let you remove or re-enable an extension
On an organization-managed device, a policy may be enforcing the extension’s state. Contact the organization’s administrator rather than attempting to bypass the policy. The allowlist, blocklist, force-install and re-enable-prevention settings described by Microsoft are administrative controls, not browser errors.
When Firefox troubleshooting information is limited
The cited Mozilla help page documents viewing, enabling, disabling, removing and managing extensions but does not specify a separate repair workflow or per-site access matrix. Start by disabling the extension, checking its settings and removing it if the problem persists. Reinstall only from Mozilla’s official add-on source after confirming that the extension is still maintained.
A practical maintenance routine
- Review the extension list every few months and remove tools you no longer use.
- Keep only the minimum site access and private-window access required.
- Investigate any extension that appears after installing unrelated Windows software.
- Use the browser’s own manager for routine changes; avoid third-party “extension manager” downloads.
- On a work or school computer, treat enforced settings as administrator policy and ask the administrator for changes.
Using the built-in manager, limiting permissions and removing extensions that alter browser behavior unexpectedly keeps add-ons under control without adding another management utility to Windows.
