How to Tell If a Browser Extension Is Safe to Keep

If you've ever noticed a strange button in your browser's toolbar, or a search bar that isn't the one you remember, it may be a browser extension you didn't mean to add. A browser extension is a small add-on program that attaches itself to your web browser — like Chrome, Edge, or Safari — to add a feature, such as a coupon finder or a weather widget.

Most extensions are harmless. But some sneak onto a computer bundled with other software, or get installed by accident when you click the wrong button on a download page. A bad one can change your search engine, fill your screen with ads, or quietly watch what you type.

The good news is that checking your extensions takes a few minutes, and removing one you don't trust is just as quick. Here's how to do it on each browser, and how to tell the safe ones from the risky ones.

Where to find your extensions

The steps are a little different depending on which browser you use. If you're not sure which one you have, look for the icon you click to open the browser — Chrome's is a colorful circle, Edge's is a blue-green wave, and Safari's is a blue compass.

In Chrome:

Click the three-dot menu (⋮) in the top-right corner of the window.
Choose Extensions, then Manage Extensions.
You'll see a list of every extension installed, along with an on/off switch for each.

In Microsoft Edge:

Click the three-dot menu (…) in the top-right corner.
Choose Extensions, then Manage Extensions.
The list works the same way — a toggle switch next to each one.

In Safari (on a Mac):

Click Safari in the menu bar at the top of the screen.
Choose Settings (on older versions of the Mac operating system, this may say Preferences).
Click the Extensions tab to see everything installed.

Signs an extension may not be safe

Once you can see the list, look for a few warning signs:

You don't remember installing it. If a name doesn't ring a bell at all, that's worth a closer look.
It asks for a lot of access. Chrome and Edge show a short description of what each extension can do, such as "read and change all your data on websites you visit." That's normal for some tools, like an ad blocker, but worth noticing.
It showed up around the same time as a problem. If your homepage changed, or pop-ups started, right around when a new toolbar appeared, that's a strong clue.
It has a vague or generic name, like "Search Helper" or "PDF Tool," especially one you don't recall choosing on purpose.

None of these alone proves an extension is harmful. But if more than one applies, it's reasonable to remove it.

How to remove an extension you don't trust

Removing one is simple, and it won't delete any files, photos, or documents on your computer — only the add-on itself.

In Chrome or Edge: on the Extensions page, find the one you want gone and click Remove. You may be asked to confirm.

In Safari: on the Extensions tab, select the extension and click Uninstall.

After removing an extension, it's a good idea to restart the browser. If your homepage or search engine had changed, go back into your browser's settings afterward and set them back to the one you prefer.

What to do if you're stuck

If you're not sure whether something is safe, or you've already removed it and something still looks wrong — your homepage keeps resetting, or ads keep popping up — that's a sign something deeper may be going on. Porchswing's hands-on help, in your home or remotely, can take a look rather than you having to guess.

Common questions

Will removing an extension delete my bookmarks or saved passwords?

No. Removing a browser extension only takes away that one add-on. Your bookmarks, saved passwords, and browsing history stay exactly where they are.

Can an extension be unsafe on my phone too?

Browser extensions mainly apply to desktop and laptop browsers like Chrome, Edge, and Safari on a Windows PC or Mac. Phone browsers handle add-ons differently, so the steps above are for your computer.

What if I can't tell which extension is causing a problem?

Try turning extensions off one at a time using the toggle switch, rather than removing them right away, and see which one is behind the change.
