We have created browser plugins for Chrome, Firefox. These plugins allow you to highlight text on any website, right-click and search Q posts for that text. These will work on Desktops, Firefox plugin may work on Firefox for Android (Chrome for Android does not support extensions). Unfortunately, Apple iOS devices do not support these types of plugins. Chrome extension may work on the Brave browser. If you use and like the extension please rate it.
