This is where a “Find and Replace Text” function is useful. However, there are times where you are writing your blog post, typing a comment, composing emails or moderating forums, and find yourself wanting to replace a couple of words that appear multiple times throughout. That’s why you seldom find text-editing features like “Find and Replace Text” in the browser. It is not meant to be used as a text editor.
A browser, as its name implies, is meant for browsing the Web.
