If Touch To Search is gone for you and you'd like it back, Just follow below steps to re-enabling the feature
- It's as easy as flipping a switch in Chrome's digital toolbox, the flags page. Head to chrome://flags page by entering it into the URL field, then search for the option called "Enable Contextual Search" (you can use the "Find in page" option to search for that, or "#contextual-search"). Enable that option, then close Chrome and re-open it.
- Once you've launched the app again, go into the Settings menu and tap "Privacy." There's an option at the bottom od the page called "Touch to Search." Set that to "On," and you're good to go. The feature should now be available on all web pages. This should work for Chrome stable, beta, and dev. Enjoy!
