I checked the changelog but there is no mention of this change. One of the features removed with this change was a way to import the device dimensions and properties into the Emulated Devices panel. Is there any place to read up on this change and its reasoning? Even if it's a pull request I'd be happy. 回答1: Source code is

问题 As the title says, I need to debug a website opened with mobile Chrome on an iOS device (iPod, iPad etc.) on Windows 10.

问题 I am using Chrome Developer tools (version 49). Under the Network tab, there is a series of columns such as Name, Status, Type..etc. Does anyone know what the purpose of the Connection ID column Each row has an ID such as 13461, 14410, 8738, 8741, 13516.... Also what do the numbers mean? 回答1: HTTP uses a networking protocol called TCP behind the scenes. Browsers maintain pools of TCP sockets and connections. The Connection ID numbers in DevTools refer to a particular TCP connection. Why are

问题 As per usual when making automated tests I use "Inspect"(CTRL+SHIFT+I) in Chrome to find element by xpath, id, CSS selector etc. For example: //li/a[contains(text(), "Products")] Above is an xpath from this page. In previous versions of Chrome in "DevTools"/"Elements" after pressing CTRL+F to open the "Find" option and pasting this xpath element is highlighted in DevTools window. In new version of chrome it is not highlighted, the usual "1/1" results is displayed in far right of the "Find"
