Video version of the release notes:
Search across all network headers and responses
Open the Network panel then press Command+F (Mac) or Control+F (Windows, Linux, Chrome OS) to open the new Network Search pane. DevTools searches the headers and bodies of all network requests for the query that you provide.

cache-control
with the new Network
Search pane
Click Match Case to make your query case-sensitive. Click
Use Regular Expression
to show any results that
match the pattern you provide. You don't need to wrap your RegEx in forward slashes.

Search pane UI updates
The UI of the Global Search pane now matches the UI of the new Network Search pane. It now also pretty-prints results to aid scannability.

Press Command+Option+F (Mac) or Control+Shift+F (Windows, Linux, Chrome OS) to open Global Search. You can also open it via the Command Menu.
CSS variable value previews in the Styles pane
When the value of a CSS color property, such as background-color
or color
, is set to
a CSS variable, DevTools now shows a preview of that color.

color: var(--main-color)
, whereas in the new UI on the right, there is
Copy as fetch
Right-click a network request then select Copy > Copy As Fetch to copy the
fetch()
-equivalent code for that request to your clipboard.

fetch()
-equivalent code for a request
DevTools produces code like the following:
fetch("https://preload.glitch.me/styles.css", {
"credentials": "omit",
"headers": {},
"referrer": "https://preload.glitch.me/after/",
"referrerPolicy": "no-referrer-when-downgrade",
"body": null,
"method": "GET",
"mode": "cors"
});
Audits panel updates
New audits
The Audits panel has 2 new audits, including:
- Preload key requests. Preloading requests can speed up page load time by giving hints to the browser to download resources that are important for your Critical Rendering Path as soon as possible.
- Avoid invisible text while webfonts are loading. Ensuring that text is visible while webfonts load makes the page more useful to users faster.
New configuration options
You can now configure the Audits panel to:
- Preserve desktop viewport and user agent settings. In other words, you can prevent the Audits panel from simulating a mobile device.
- Disable network and CPU throttling.
- Preserve storage, such as LocalStorage and IndexedDB, across audits.

View traces
After auditing a page, click View Trace to view the load performance data that your audit is based off of in the Performance panel.

Stop infinite loops
If you work with for
loops, do...while
loops, or recursion a lot, you've probably executed
an infinite loop by mistake while developing your site. To stop the infinite loop, you can now:
- Open the Sources panel.
- Click Pause
. The button changes to Resume Script Execution
.
- Hold Resume Script Execution
then select Stop Current JavaScript Call
.
In the video above, the clock is being updated via a setInterval()
timer. Clicking
Start Infinite Loop runs a do...while
loop that never stops. The interval resumes because
it wasn't running when Stop Current JavaScript Call was selected.
User Timing in the Performance tabs
When viewing a Performance recording, click the User Timing section to view User Timing measures in the Summary, Bottom-Up, Call Tree and Event Log tabs.

In general, you can now select any of the sections (Main Thread, User Timing, GPU, ScriptStreamer, and so on) and view that section's activity in the tabs.
Select JavaScript VM instances in the Memory panel
The Memory panel now clearly lists out all JavaScript VM instances associated with a page, rather than hiding them behind the Target dropdown menu as before.

Next to the developers.google.com
instance there are 2 values: 8.7 MB
and 13.3 MB
.
The left value represents memory allocated because of JavaScript. The right value represents all
OS memory that is being allocated because of that VM instance. The right value is inclusive
of the left value. In Chrome's Task Manager, the left value corresponds to JavaScript Memory
and the right value corresponds to Memory Footprint
.
Network tab renamed to Page tab
On the Sources panel, the Network tab is now called the Page tab.

Dark theme updates
Chrome 67 ships with a number of minor changes to the dark theme color scheme. For example, the breakpoint icons and the current line of execution are now green.

Certificate transparency in the Security panel
The Security panel now reports certificate transparency information.

Site Isolation in the Performance panel
If you've got Site Isolation enabled, the Performance panel now provides a flame chart for each process so that you can see the total work that each process is causing.
