Link your local chromium code path to remote source.chromium.org.
You can install this extension from the Visual Studio Marketplace.
Tips: to enable the ability to link remote source.chromium.org code path to your local chromium src, you should also install related Chrome Extension/MSEdge Extension.
Right-click on the line you want to visit on remote source.chromium.org.
For example in //base/values.h:104
Then the same line will be opened in the browser on remote source.chromium.org.
And one tip message will show on the right-bottom of your VsCode Browser if the open operation is executed successfully.
(No need to worry about, it will disappear in several seconds or you can close it manually. :))
Enjoy!
