How to View All Browser Extensions Installed
This guide shows you how to list every extension installed in Chrome, Firefox, Edge, Safari, and Opera, plus how to get a combined view across all your browsers. It’s for anyone who manages multiple browsers, wants to audit for unused or suspicious add-ons, or simply needs a quick inventory before switching devices.
1. Chrome: The Extensions Page
Open Chrome and type chrome://extensions in the address bar, then press Enter. This loads the full management page, showing every extension with its name, version, and enabled status. Use the toggle on each card to disable one, and click “Details� to see permissions, site access, and the install date. For a quick count, the page header shows “Extensions (N)� above the list.
2. Edge: Built on Chromium, Same Shortcut
Since Edge is Chromium-based, it uses a similar internal page: type edge://extensions in the address bar. The layout mirrors Chrome’s, with a list of all installed extensions and toggles for each. You can also click the puzzle-piece icon in the toolbar and select “Manage extensions� to reach the same page. Edge also shows the version number and permissions for each add-on, which helps when comparing across browsers.
3. Firefox: about:addons
Firefox uses about:addons as its add-on manager, which you can type directly into the address bar. This page has tabs for Extensions, Themes, Plugins, and Updates. The Extensions tab lists all installed add-ons with a status indicator (enabled/disabled) and a gear icon for more options. To see detailed information like version and ID, click the extension’s name. You can also search within the list using the search bar at the top.
4. Safari: The Settings Pane
In Safari on macOS, go to Safari > Settings (or Preferences in older versions) and click the Extensions tab. This shows every installed extension with a checkbox to enable or disable it. Safari also lists the extension’s website and version. On iOS/iPadOS, you’ll find extensions in Settings > Safari > Extensions, which shows a similar list with toggles. Note that Safari extensions are often bundled with apps, so the list may include extensions from apps you’ve installed.
5. Opera: opera://extensions
Opera, also Chromium-based, uses opera://extensions as its internal URL. This page displays all installed extensions in a card layout, similar to Chrome. You can enable/disable each with a toggle, and click “Details� to see permissions and version info. Opera also has a “Developer mode� switch that reveals additional technical details like the extension’s ID and path on disk.
6. Brave: Brave://extensions
Brave, another Chromium browser, uses brave://extensions to list its add-ons. The interface is nearly identical to Chrome’s, with toggles and details for each extension. Brave also includes a “Brave Rewards� and “Wallet� section, but those are separate from extensions. This page is the fastest way to see what’s installed and to remove any that you no longer need.
7. Vivaldi: vivaldi://extensions
Vivaldi, also Chromium-based, has its own URL: vivaldi://extensions. This opens the same type of management page, listing all extensions with enable/disable toggles. Vivaldi also supports “Sessions� and “Panels� that can be extensions, but the main list is here. If you use Vivaldi’s built-in features like “Web Panels,� they won’t appear in this list—only true extensions do.
8. Cross-Browser Audit with a Third-Party Tool
If you need a combined list from multiple browsers, use a free tool like Browser Extensions List or Extension Manager (both are web apps that read from your browsers’ profile folders). These tools scan your local browser profiles and output a single report. However, they require you to grant access to your profile directories, so only use reputable tools and be cautious with sensitive data. Alternatively, you can manually export each browser’s list using the steps above and compile them in a spreadsheet.
9. Command-Line Method for Windows and macOS
For a scripted approach, you can list extensions by reading the browser’s profile files directly. On Windows, Chrome’s extensions are stored in %LOCALAPPDATA%\Google\Chrome\User Data\Default\Extensions, and each subfolder is an extension ID. On macOS, the path is ~/Library/Application Support/Google/Chrome/Default/Extensions. You can use a terminal command like ls to see the IDs, but you’ll need to cross-reference with the manifest.json file inside each folder to get the name. This method is technical and best for advanced users who want to automate audits.
10. Using the Browser Profile to See Hidden Extensions
Some extensions are “hidden� from the standard page because they are managed by an enterprise policy or installed by an app. To view these, look for the “Managed by your organization� banner on the extensions page. In Chrome, you can also type chrome://policy to see any forced extensions. For a complete list, check the browser’s profile folder for a file named Preferences (Chrome/Edge) or extensions.json (Firefox). These files contain the full list of installed extensions, including those that are disabled or hidden.
How to Choose
When deciding which method to use, consider your primary goal. If you just need a quick glance at one browser, the internal page (chrome://extensions, etc.) is fastest. For a cross-browser inventory, a third-party tool saves time but requires trust. The command-line method is best for scripting and automation, but it’s error-prone if you’re not comfortable with file systems. Also, note that some browsers like Chrome and Edge sync extensions across devices, so your list may vary per device; check the sync settings to see if you’re viewing the full set.
Frequently Asked Questions
Q: Can I see extensions that are disabled?
A: Yes, the extensions page shows all installed extensions, including disabled ones, with a toggle to re-enable them.
Q: Why do I see extensions I didn’t install?
A: Some software installs extensions as part of its setup, or they may be synced from another device. Check the extension’s details for the install source.
Q: How do I remove an extension completely?
A: On the extensions page, click “Remove� or the trash icon. For Chrome and Edge, you can also right-click the extension icon and choose “Remove from Chrome.�
Q: Can I export my extension list to a file?
A: Not directly, but you can copy the list manually or use a third-party tool that exports to CSV or text.
Q: Are extensions synced across browsers?
A: Only if you’re signed in to the same browser account (e.g., Chrome sync). Extensions are not shared between different browsers like Chrome and Firefox.
Q: What if the internal page is blank?
A: This can happen if the browser profile is corrupted. Try restarting the browser, or check if you’re in incognito mode (extensions are disabled there). If the issue persists, reset the browser settings.
Final Thoughts
Knowing how to list your extensions is the first step toward keeping your browser clean and secure. Regularly auditing your extensions helps you spot ones you no longer use, which can improve performance and reduce privacy risks. Start with the built-in page for each browser, and only go the third-party route if you need a combined view. With these methods, you’ll never lose track of what’s running in your browsers again.
