How to Enable Enhanced Tracking Protection in Firefox

Firefox blocks most trackers out of the box, so the setting you are looking for may already be on. The real question is whether the default level is enough or whether you should step up to Strict.

Open Settings, then Privacy & Security, and check the current level first. If a site breaks, use the shield in the address bar to make an exception for that one site instead of weakening protection everywhere.

In this guide, I have covered:

Check Whether Firefox Tracking Protection Is Already On

Firefox starts blocking trackers the moment you install it, so there is no on/off switch waiting to be found. What you control is the level, and it lives in the privacy settings.

Mozilla explains the feature in its Enhanced Tracking Protection support guidance. The Firefox protection page covers what the browser blocks and why.

1. Open the menu in the upper-right corner of Firefox.
2. Select Settings.
3. Select Privacy & Security in the Settings sidebar.
4. Scroll to Enhanced Tracking Protection and check which level is selected.

Seeing Standard selected means protection is already on. Move to Strict when you want tracking content blocked in normal and private windows alike.

Choose the Right Tracking Protection Level

Three levels, one decision, and it applies to every site until you make an exception. Standard is what you get out of the box. Strict applies stronger blocking across regular and private windows.

1. Open the menu in the upper-right corner of Firefox.
2. Select Settings.
3. Select Privacy & Security in the Settings sidebar.
4. Find Enhanced Tracking Protection.
5. Select Strict to strengthen tracking protection in all windows.

Reload any page that is already open so the new level takes effect. The shield in the address bar shows what is running on the site in front of you.

TIP: If Strict breaks a site you rely on, do not lower the level for everything. Open the shield on that site and turn protection off there instead.

Create a Custom Tracking Protection Setup

Standard feels too loose, or Strict keeps breaking something you need. That is the point where picking categories yourself beats choosing a preset.

The trade-off is more clicks and some testing. You choose what Firefox blocks, then check the sites you care about.

1. Open the menu in the upper-right corner of Firefox.
2. Select Settings.
3. Select Privacy & Security in the Settings sidebar.
4. Find Enhanced Tracking Protection.
5. Select Custom.
6. Select Advanced settings.
7. Choose which trackers and scripts Firefox should block.

Save the changes and reload the affected site. If an important page still will not load, review the categories you changed before falling back to Standard or Strict.

Check Protection for the Current Website

Not sure Firefox is doing anything on the page in front of you? The address bar answers that in one click.

A shield sits at the left end of the address bar. It reports what Firefox blocked on that page and which level is in force.

1. Open the website you want to check in Firefox.
2. Select the shield in the address bar.
3. Review the trackers and scripts Firefox reports as blocked.

A shield with a check mark means protection is active. The panel also shows how many items Firefox blocked during your visit.

Turn Off Tracking Protection for One Site

Some sites need their trackers to sign you in or load a widget. When that happens, you want an exception for one site, not a weaker setting for every site.

Firefox lets you pause protection from the address bar. The exception holds until you undo it, and every other site keeps the level you picked.

1. Open the website that fails to load in Firefox.
2. Click the shield icon to the left of the address bar.
3. Toggle the switch labeled "Enhanced Tracking Protection is ON for this site" so it moves to OFF.
4. Wait for Firefox to reload the tab automatically, then try the page again.

You’ll know it worked when the page loads normally and the shield stops showing protection as on for that site. Once the site behaves, reopen the shield and turn protection back on.

Manage Tracking Protection Exceptions

Exceptions pile up quietly. If a site you allowed months ago still shows protection as off, this list is where you clear it.

Firefox keeps every allowed site in the privacy settings, which beats hunting through bookmarks for a page you unblocked.

1. Open the menu in the upper-right corner of Firefox.
2. Select Settings.
3. Select Privacy & Security in the Settings sidebar.
4. Find Enhanced Tracking Protection.
5. Select Advanced settings.
6. Open the exceptions list.
7. Select a website and choose the option that removes its exception.

Back in the exceptions list, confirm the site is gone. Reload that site to apply the updated protection.

If a protected website stops loading correctly, check its shield and the exceptions list before lowering your global protection level. A site-specific exception is safer than changing protection for every website.

Troubleshoot Settings That Do Not Change

You changed the level and the page still looks the same. Usually the page was loaded before you made the change.

Reload it first, because some sites read the protection status only when they load. To skip the menus, type about:preferences#privacy in the address bar and press Enter.

If the page still behaves as though protection is off, check the exceptions list. When the problem looks like stale site data rather than a setting, resetting the site is the next step. Here is how to clear cookies and cache in Firefox without touching your protection level.
