 Analytics.js stores events in `localStorage` and falls back to in-memory storage when `localStorage` is unavailable. It retries up to 10 times with an incrementally increasing backoff between each retry. Analytics.js queues up to 100 events at a time to avoid using too much of the device's local storage. See the [destination Retries documentation](/docs/connections/destinations/#retries) to learn more.

-## Proxying Analytics.js
-
-To use a proxy server with Analytics.js, first change the `cdn.segment.com` address in the snippet to use your own host. Next, [contact Segment Product Support](https://segment.com/help/contact/) and request to change the endpoint Segment sends your events to so that is uses your proxy instead. Make sure that your proxy behaves exactly like the Segment APIs. You can use [the Segment proxy server](https://github.com/segmentio/segment-proxy) as an example of a correctly-working proxy.

+
+[The Segment JavaScript library, Analytics.js](https://segment.com/docs/connections/sources/catalog/libraries/website/javascript/), loads a snippet on your webpage that supports existing user consent APIs and native browser controls. Segment regularly tests Analytics.js against the following browsers on all major platforms, and updates the library accordingly.
+
+The library is regularly tested and is functional with the following browsers:
+
+- Internet Explorer
+- Apple Safari
+- Google Chrome
+- Mozilla Firefox
+- Microsoft Edge
+- Brave
+
+### Internet Explorer Support
+
+Segment guarantees support for Internet Explorer 11 and later for Analytics.js. Remember that different bundled (device-mode) destinations might have different compatibility guarantees for their own products. Refer to the vendor’s documentation to confirm browser compatibility.
+
+
+## Tracking Protection (ITP, ETP)
+
+Segment is a customer data platform (CDP) that helps companies harness first-party customer data. The recent browser changes fully align with Segment’s privacy stance.
+
+Browser manufacturers have enhanced their privacy features by adding third-party tracking protection mechanisms for end-users. These browser changes target third-party trackers and their cookies, and each platform takes a different approach.
+
+For example, [Firefox Enhanced Tracking Protection (ETP)](https://blog.mozilla.org/blog/2020/08/04/latest-firefox-rolls-out-enhanced-tracking-protection-2-0-blocking-redirect-trackers-by-default/) relies on a dynamic list of known trackers to decide what to block. Browsers that use [Apple’s Webkit engine](https://webkit.org/blog/10218/full-third-party-cookie-blocking-and-more/), like Safari and Chrome for iOS, use Intelligent Tracking Protection (ITP) which actively prevents the browser from loading cookies from a third-party domain.
+
+> info ""
+> **Note:** Segment cookies expire after seven days of user inactivity, like all other application cookies under the Webkit engine ITP policy.
+
+## Proxying Analytics.js
+
+Because of regulatory, environmental, or security concerns, some customers prefer to set up proxy infrastructure for Analytics.js. You can use the `apihost` configuration option in the Analytics object to route traffic to different API endpoints. Business Tier customers can use Segment’s fully-managed proxy service: In-domain Instrumentation, which provides a similar function without the additional maintenance burden and cost of running your own proxy infrastructure.

-## Do you have any ad blockers enabled in your browser?
-
-Segment and many destination partners use cookies/local storage to store information about users in the browser. Ad blockers prevent cookies and other data these tools rely on to make valid analytics requests. Some portion of your users are probably using ad blockers, which prevent the Segment script from fully executing. Both desktop and mobile browsers are impacted.

-One particular issue is Safari private browsing mode which allows Analytics.js Identify calls to be made, but the traits object is stripped from the call. This results in identify calls missing email address and other traits.

 For example, imagine that your website allows users to view a receipt for purchases at the URL `https://mywebsite.com/store/purchases`.  Your users click a link that redirects to that specific URL, your app sets a `receiptId` in the query string, and returns the appropriate receipt.  You also send a Track call to Segment from this page.
