Indeed the only way to use the Find and Replace dialog in Html mode of the editor is to set the ToolBarMode
property to Default. How ever this feature is available only in Internet Explorer browser. In FireFox the dialog does not work in Html (source) mode due to browser restrictions. It is possible to search for a string in a TextArea in Firefox using the window.find(string)
method only. This method however does not work as expected, because it finds only the first occurrence of a string in the text of the textarea and it does not find the following occurrences. In Opera it is not possible to find a text at all in a TextArea and since we want to offer only cross browser features, for a long time we have been deciding not to provide a Find & Replace dialog in HTML mode in all browsers. However due to a lot of user request we enabled it in IE a couple of versions ago.
