So within every other modern browser, ctrl+F can find values of input fields. In IE(X), however, it doesn't find it at all. Is there a way to get the find functionality to find those values? Or is there an attribute/tag/property that can be used to get that functionality?
It needs to find values in input tags.
You can use the IE developer tools, it has its own "Search for items" where you can find specific text inside the markup
