How to delete an add-on depends on which browser you use
The steps to remove an add-on are different in Chrome, Firefox, Safari, and Edge. Each browser stores extensions in a different place and uses different names for the same thing — Chrome calls them "extensions," Firefox calls them "add-ons," Safari calls them "extensions," and Edge calls them "extensions." The process takes less than a minute once you know where to look, and removing add-ons you don't use is one of the fastest ways to improve browser speed and reduce what programs can see about your browsing.
You should delete an add-on if you no longer use it, if it's slowing down your browser, or if you're concerned about what data it collects. Removing it completely — rather than just turning it off — means the program no longer has access to your browsing history or the websites you visit.
Key Takeaways
- In Chrome, go to the menu icon (three dots), select "More tools," then "Extensions," and click the trash icon next to any add-on you want to remove.
- In Firefox, click the menu icon (three horizontal lines), select "Add-ons and themes," find the add-on, and click "Remove."
- In Safari, go to Safari menu, select "Preferences," click the "Extensions" tab, select the add-on, and click "Uninstall."
- In Edge, click the menu icon (three dots), select "Extensions," find the add-on, and click "Remove from Microsoft Edge."
- Restarting your browser after deletion ensures the add-on is fully removed and no longer running in the background.
Removing add-ons in Google Chrome
Open Chrome and click the three-dot menu icon in the top right corner. Select "More tools" from the dropdown, then click "Extensions." You will see a list of every extension currently installed in your browser, with a toggle switch next to each one.
Find the extension you want to remove and click the trash icon below its name. Chrome will ask you to confirm the deletion. Click "Remove" in the popup window. The extension disappears when ready, and Chrome will no longer load it when you open the browser.
If you want to see what data an extension has collected before you delete it, click on the extension's name instead of the trash icon. This opens a details page that shows what permissions the extension has — for example, whether it can see all your browsing history or only the websites where you use it. You can also turn off the extension temporarily by toggling the switch off, which disables it without removing it completely.
Removing add-ons in Mozilla Firefox
Click the menu icon (three horizontal lines) in the top right corner of Firefox. Select "Add-ons and themes" from the menu. Firefox opens a new tab showing all your installed add-ons, organized by type — extensions, themes, plugins, and dictionaries.
Find the add-on you want to remove in the extensions section. Click the three-dot menu next to its name and select "Remove." Firefox removes the add-on when ready. If you want to turn it off without deleting it, click the toggle switch next to the add-on's name instead.
Firefox also shows you what permissions each add-on has — click on the add-on's name to see whether it can access your browsing history, read and change data on websites you visit, or access your downloads. This information helps you decide whether to keep an add-on or remove it.
Removing add-ons in Apple Safari
Click the Safari menu at the top of your screen and select "Preferences" (or "Settings" on newer versions of macOS). Click the "Extensions" tab at the top of the preferences window. You will see a list of all installed extensions on the left side.
Click the extension you want to remove, then click the "Uninstall" button. Safari asks you to confirm. Click "Uninstall" again, and the extension is removed. Unlike Chrome and Firefox, Safari does not show a list view of all extensions at once — you have to select each one individually to see its details.
If you want to turn off an extension without removing it, uncheck the box next to its name in the extensions list. The extension stays installed but does not run until you check the box again.
Removing add-ons in Microsoft Edge
Click the three-dot menu icon in the top right corner of Edge. Select "Extensions" from the menu. Edge opens a sidebar on the right showing all your installed extensions.
Find the extension you want to remove and click the three-dot menu next to its name. Select "Remove from Microsoft Edge." Edge asks you to confirm the removal. Click "Remove," and the extension is deleted. You can also toggle the extension off without removing it by clicking the toggle switch next to its name.
Edge also allows you to manage extensions from the Extensions menu by clicking "Manage extensions" at the bottom of the sidebar. This opens a full page view similar to Chrome's extension manager, where you can see all your extensions at once and review their permissions.
What happens when you delete an add-on
When you remove an add-on, the browser stops loading it when ready. The program no longer has access to your browsing history, the websites you visit, or any data it was collecting. However, data the add-on already collected before you deleted it remains on your computer or on the company's servers — deleting the add-on does not erase past activity.
If you reinstall the same add-on later, it may remember some settings or data, depending on how the add-on was designed. Most add-ons do not store much data locally, but some do. If you want to completely remove all traces of an add-on, you can clear your browser cache and cookies after deleting it, though this also clears data from other websites and services.
After you delete an add-on, restart your browser to make sure it is fully removed and not running in the background. Some add-ons continue to run briefly even after you delete them, and restarting ensures a clean break.
Why you might want to delete add-ons you're not using
Every add-on running in your browser uses memory and can slow down page load times. If you have many extensions installed, removing the ones you don't use regularly can noticeably speed up your browser. This is especially true on older computers or devices with limited memory.
Add-ons also have access to your browsing data. Even if an add-on is not actively collecting information, it has permission to see which websites you visit and what you do on them. Removing add-ons you don't trust or don't use reduces the number of programs that can see your online activity. If you installed an add-on months ago and have forgotten what it does, it's usually safer to delete it than to leave it running in the background.
Some add-ons request broad permissions — for example, permission to "read and change all your data on all websites you visit." This means the add-on can see and modify anything on any website. Deleting add-ons with overly broad permissions reduces your exposure to programs that could misuse that access.
Frequently Asked Questions
Can I recover an add-on after I delete it?
Yes. You can reinstall any add-on from your browser's official store — the Chrome Web Store, Firefox Add-ons, Safari App Store, or Microsoft Edge Add-ons. Search for the add-on by name and click "Add to [browser]" or the equivalent button. Your browser settings may be restored if the add-on saves them to your account, but data the add-on collected before you deleted it is usually gone.
What's the difference between disabling and deleting an add-on?
Disabling (or turning off) an add-on stops it from running, but it stays installed on your computer. The add-on still takes up storage space and can be turned back on with one click. Deleting removes it completely. If you think you might use an add-on again soon, disable it. If you're sure you won't use it, delete it.
Will deleting an add-on affect my saved passwords or bookmarks?
No. Deleting an add-on does not affect passwords, bookmarks, browsing history, or any other browser data. These are stored separately from extensions. The only exception is if the add-on itself was a password manager or bookmark manager — in that case, you should export your data before deleting it.
Why does an add-on keep coming back after I delete it?
Some add-ons are installed by other software on your computer and reinstall themselves automatically. If an add-on reappears after you delete it, check your computer for other programs that might be installing it. You may need to uninstall the parent program or change its settings to stop it from reinstalling the add-on.
Can I delete all my add-ons at once?
Most browsers do not have a "delete all" button. You have to remove each add-on individually. However, if you want a fresh start, you can reset your browser to its default settings, which removes all extensions. In Chrome, go to Settings, click "Reset and clean up," then "Restore settings to their original defaults." In Firefox, click the menu, select "Help," then "Troubleshoot Information," and click "Refresh Firefox." This removes all add-ons but keeps your bookmarks and passwords.
