Avoid chaining critical requests - 11 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.

Preload key requests
Consider using `` to prioritize fetching resources that are currently requested later in page load. Learn more.

User Timing marks and measures
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn more.

Use video formats for animated content
Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes. Learn more.

Server response times are low (TTFB) - Root document took 30 ms
Time To First Byte identifies the time at which your server sends a response. Learn more.

Efficiently encode images
Optimized images load faster and consume less cellular data. Learn more.

Network Round Trip Times - 0 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance. Learn more.

All text remains visible during webfont loads
Leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Learn more.

Preconnect to required origins
Consider adding `preconnect` or `dns-prefetch` resource hints to establish early connections to important third-party origins. Learn more.

Minify CSS
Minifying CSS files can reduce network payload sizes. Learn more.

Server Backend Latencies - 0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance. Learn more.

Defer offscreen images
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn more.

Remove unused CSS
Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity. Learn more.

Efficiently encode images
Optimized images load faster and consume less cellular data. Learn more.

Network Round Trip Times - 0 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance. Learn more.

All text remains visible during webfont loads
Leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Learn more.

Minify CSS
Minifying CSS files can reduce network payload sizes. Learn more.

Server Backend Latencies - 0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance. Learn more.

Properly size images
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.

Remove unused CSS
Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity. Learn more.

Avoid chaining critical requests - 11 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.

Avoid landing page redirects

Your page has 3 redirects. Redirects introduce additional delays before the page can be loaded.

Avoid landing page redirects for the following chain of redirected URLs.

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 5 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.Remove render-blocking JavaScript:

https://www.mozilla.org/media/js/BUNDLES/site.133e404d326d.js
https://www.mozilla.org/media/js/BUNDLES/gtm-snippet.9f9cf2026c5f.js

https://www.mozilla.org/media/css/BUNDLES/home-2018.00d7b2b54843.css

Optimize images

Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 192KiB (25% reduction).

Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_11/dev-high-res.231b9c104561.jpg could save 85.1KiB (33% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_1/corona.3e7e58e93824.jpg could save 18.7KiB (25% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_3/pass-high-res.3117d703cdda.jpg could save 18.6KiB (28% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_9/shop-high-res.9c0637f1538e.jpg could save 14.2KiB (24% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_8/irl-high-res.608df7e8cda3.jpg could save 13.7KiB (28% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_15/hubs-high-res.9a3448dfd0af.jpg could save 13.5KiB (17% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_2/ceo-high-res.d7f494f328aa.jpg could save 12.1KiB (18% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_10/colour-high-res.97a99fbdc0d7.jpg could save 10.1KiB (12% reduction).
Compressing https://www.mozilla.org/media/contentcards/img/home-2019/card_16/graph-high-res.9567377bd0cd.jpg could save 6KiB (19% reduction).

Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.

180.8KiB of the HTML response was required to render the above-the-fold content. This requires 4 network round-trips. However, if the HTML response were compressed, then the HTML required to render the above-the-fold content could be delivered in just 2 network round-trips. Enable compression for the HTML response in order to prioritize the visible content for this page.

Only about 8% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.
Click to see the screenshot with 2 round trips:

Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.

Enable compression for the following resources to reduce their transfer size by 152KiB (85% reduction).

Compressing https://www.mozilla.org/en-US/ could save 152KiB (85% reduction).

Minify HTML

Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and p*** times.

Minify HTML for the following resources to reduce their size by 33.6KiB (19% reduction).

Minifying https://www.mozilla.org/en-US/ could save 33.6KiB (19% reduction).

Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

https://www.googletagmanager.com/gtm.js?id=GTM-MW3R8V&l=dataLayer (15 minutes)
https://img-getpocket.cdn.mozilla.net/direct?url=https%3A%2F%2Fopencovidpledge.org%2Fwp-content%2Fuploads%2F2020%2F03%2FOCP_tw_lg.png&resize=w450 (26.4 minutes)
https://www.google-***ytics.com/plugins/ua/linkid.js (60 minutes)
https://www.google-***ytics.com/***ytics.js (2 hours)

Size tap targets appropriately

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

The tap target <a href="https://foundation.mozilla.org">Mozilla Foundation</a> is close to 1 other tap targets.
