How to delete an extension depends on your browser
The steps to remove an extension differ between Chrome, Firefox, Safari, and Edge. Each browser stores extensions in a different menu, and the process takes less than a minute once you find the right place. You do not need to uninstall anything from your computer — removing an extension from the browser itself is all that happens.
Extensions can slow down your browser, use your data, or request access to sites you visit. Deleting ones you no longer use is a straightforward way to improve performance and privacy. The extension stops working immediately after removal, and you can reinstall it later if you change your mind.
Key Takeaways
- Chrome extensions are removed through the three-dot menu under "More tools" → "Extensions", where you click the trash icon next to the extension name.
- Firefox extensions are found in the menu button (three horizontal lines) under "Add-ons and themes", where you click the three dots next to the extension and select "Remove".
- Safari extensions are managed in Safari Preferences under the "Extensions" tab, where you uncheck the box next to the extension to disable it or click "Uninstall" to remove it completely.
- Edge extensions are removed through the three-dot menu under "Extensions", where you click "Manage extensions" and then the trash icon next to the extension you want to delete.
- Removing an extension does not delete your browser history, passwords, or other data — only the extension itself is removed.
Deleting extensions in Chrome
Open Chrome and click the three-dot menu in the top right corner. Select "More tools" and then "Extensions". You will see a list of all installed extensions with a trash icon next to each one. Click the trash icon next to the extension you want to remove, and a confirmation box will appear asking if you want to remove it. Click "Remove" to confirm.
After deletion, the extension stops working immediately. If you want to see what extensions are currently active, you can also click the puzzle-piece icon (or extension icon) in the top right of Chrome to see a dropdown list of your extensions. From there, you can click the three dots next to any extension and select "Remove from Chrome".
Deleting extensions in Firefox
Click the menu button (three horizontal lines) in the top right corner of Firefox. Select "Add-ons and themes". On the left side, click "Extensions" to see your installed extensions. Find the extension you want to remove, click the three dots next to it, and select "Remove".
Firefox will ask you to confirm the removal. Click "Remove" again, and the extension is deleted. You can also disable an extension without removing it by clicking the toggle switch next to the extension name — this keeps the extension installed but turns it off. If you want to remove it later, you can always come back to this menu.
Deleting extensions in Safari
Safari handles extensions differently than other browsers. Open Safari and click "Safari" in the top menu bar. Select "Preferences" (or "Settings" on newer versions). Click the "Extensions" tab at the top. You will see a list of installed extensions on the left side.
Click the extension you want to remove, and on the right side you will see an "Uninstall" button. Click it to remove the extension completely. If you only want to turn off an extension temporarily without removing it, you can uncheck the box next to the extension name in the left column. The extension will remain installed but will not run until you check the box again.
Deleting extensions in Edge
Click the three-dot menu in the top right corner of Edge. Select "Extensions" and then "Manage extensions". You will see all your installed extensions listed. Find the one you want to delete and click the trash icon next to it. Edge will ask you to confirm the removal. Click "Remove" and the extension is deleted.
You can also access your extensions by clicking the puzzle-piece icon in the top right corner of Edge. From the dropdown menu, click the three dots next to any extension and select "Remove from Microsoft Edge". Both methods work equally well — use whichever is faster for you.
What happens when you delete an extension
Deleting an extension removes it from your browser completely. The extension no longer runs, no longer has access to the sites you visit, and no longer uses your computer's memory or internet data. Your browsing history, saved passwords, bookmarks, and other browser data remain unchanged.
If you delete an extension by mistake, you can reinstall it from the same place you found it originally — the Chrome Web Store, Firefox Add-ons, Safari App Store, or Microsoft Edge Add-ons. The reinstalled extension will start fresh with no memory of its previous settings, so you may need to configure it again if it had custom options.
Why you might want to delete extensions
Extensions that you no longer use can slow down your browser, especially if you have many installed at once. Each extension runs in the background and uses memory and processing power. Removing extensions you do not actively use can make your browser faster and more responsive.
Some extensions request access to all the sites you visit, which means they can see what you are doing online. If you no longer trust an extension or do not need it anymore, removing it improves your privacy. Extensions can also become outdated or stop working properly if the developer stops maintaining them, so deleting broken extensions prevents errors and unexpected behavior.
Frequently Asked Questions
Will deleting an extension remove my saved data from that extension?
Yes, in most cases. When you remove an extension, any data it stored — like settings, preferences, or saved information — is deleted along with it. If you reinstall the extension later, it will start with default settings. Some extensions may store data in your browser's general storage, but most clear everything when removed.
Can I disable an extension instead of deleting it?
Yes. In Chrome, Firefox, and Edge, you can click the toggle switch next to an extension to turn it off without removing it. In Safari, you can uncheck the box next to the extension name. The extension remains installed but does not run. This is useful if you think you might want to use it again later.
What if I cannot find the extension I want to delete?
Some extensions hide themselves or use different names than you expect. In Chrome and Edge, click the puzzle-piece icon in the top right to see all extensions in a dropdown. In Firefox, go to Add-ons and Themes. In Safari, check Preferences under Extensions. If an extension still does not appear, it may already be removed or disabled.
Does deleting an extension affect my browser's saved passwords or history?
No. Deleting an extension only removes the extension itself. Your passwords, browsing history, bookmarks, autofill data, and all other browser information stay exactly as they are. The extension has no connection to that data unless it was specifically designed to manage passwords or history.
Can I delete multiple extensions at once?
No. All major browsers require you to delete extensions one at a time. You click the delete or remove button for each extension individually. If you have many extensions to remove, it takes a few minutes, but the process is straightforward in each browser.
