Extensions make your browser more useful, but a slow or suspicious one can ruin it — slowing pages, injecting ads, or redirecting you to scam sites. Knowing how to remove them quickly is a basic security skill.
The short answer
Open your browser's extensions page, find the extension, and remove it. If you think it is malicious, also check for other extensions you do not recognise, clear the extension's site data, and restart the browser.
When removal is urgent
Most extensions are removed for housekeeping — you stopped using them or they slowed things down. Removal is urgent when you see any of these:
- Pop-ups or injected ads on pages that never had them
- Search results that redirect through a site you did not choose
- A new homepage or new-tab page you did not set
- An extension you do not remember installing
- Login prompts on pages where the site never asked for them
Any one of these means the extension is likely doing more than it should, and you should remove it now, not later. The steps below take under a minute.
Remove an extension in Chrome
- Click the three-dot menu in the top-right corner.
- Go to Extensions → Manage extensions (or type
chrome://extensionsin the address bar). - Find the extension you want to remove.
- Click Remove and confirm.
To disable it temporarily instead of deleting, toggle it off on the same page.
Remove an extension in Firefox
- Click the menu button (three lines) in the top-right corner.
- Choose Add-ons and themes (or type
about:addonsin the address bar). - Select Extensions in the left menu.
- Find the extension, click the three-dot menu next to it, and choose Remove.
You can also turn an extension off without removing it from the same menu.
Remove an extension in Microsoft Edge
- Click the three-dot menu in the top-right corner.
- Go to Extensions (or type
edge://extensions). - Find the extension and click Remove (the bin icon).
Remove an extension in Opera
- Click the Opera menu (the "O" icon in the top-left corner).
- Choose Extensions → Extensions (or type
opera://extensions). - Find the extension and click the X to remove it.
If an extension will not uninstall
A small number of extensions are set to be "enforced" by policy (usually on a work or school computer) and will not have a working Remove button. If that happens:
- Ask your work or school administrator — the browser is managed by policy.
- As a last resort on a personal device, run a malware scanner; some "extensions" that resist removal are actually malware.
After you remove a suspicious extension
If the extension appeared without you installing it, or if you saw new pop-ups and redirects:
- Remove every extension you do not recognise, not just the obvious one.
- Close and restart the browser completely.
- Change the passwords for any account you were signed into, and enable two-factor authentication.
- Check your browser's search engine setting — hijackers often change the default search engine to one that serves ads or scams.
- Run your operating system's security scanner once to be sure nothing else arrived.
In Chrome you can also clear the data the extension stored: open chrome://settings/content/all (or Site settings → View permissions and data stored across sites), find the extension's entry, and remove it. That wipes any settings or locally saved data it left behind.
How to avoid needing this again
- Install extensions only from the official store for your browser. See our guide on how to choose safe browser extensions.
- Review what permissions an extension asks for before installing — the permissions guide explains what each one means.
- Audit your installed extensions every few months and remove anything you have not used recently.
Quick answers
What is the difference between removing and disabling an extension? Disabling stops it from running but leaves it installed, so it can be switched back on by a hijacked browser. Removing deletes it entirely. For anything suspicious, remove, do not disable.
Will removing an extension delete my data? Removing the extension deletes its locally stored data in most browsers. If you want the data back later, export it from the extension's options before removing.
An extension I use for work was removed by my administrator. Can I get it back? Only through the administrator — the policy that removed it is enforced by the work or school account.
How do I know if removing an extension broke a website? Reload the site. If a page stops working after you removed an extension, the extension was changing that page — usually by injecting content. Either accept the page looking plain or reinstall the extension and check its permissions first.
