We use a WYSIWYG editor for adding and editing content to certain websites that we support. With the latest update of Firefox, the toolbar buttons for sanitizing clipboard content as rich text or plain text become grayed out when the cursor is placed inside of the editable text area. This bug is not exhibited in any other browser, and did not occur in the previous version of Firefox. --- MORE INFORMATION * The toolbar buttons do not disappear on page load; they can still be clicked to sanitize clipboard contents before the cursor is placed inside of the editable text area. While this would not break our editing experience if we could be guaranteed that our site editors were always pasting content into empty text areas, we cannot make this assumption. Therefore, the ability to place the cursor inside the editable region before clicking on the toolbar buttons is essential and the disappearance of the buttons is a bug. * As enumerated above, this behavior has been isolated as only occurring in the Firefox browser and only on the latest version of Firefox. Attached is a screenshot of the correct behavior, toolbar buttons not disappearing upon clicking into the editable text area, in Google Chrome. * When there are multiple WYSIWYG text areas on a single page, they are impacted independently of one another. That is, clicking in one editable text area only grays out the toolbar buttons for that particular text area, and the others remain clickable until the cursor is placed inside their respective editable text areas. Clicking outside of an editable text region does not "restore" the buttons to a clickable state. Once they become grayed out, they appear to stay that way unless and until the page is reloaded. * Other toolbar buttons, such as those for inserting/removing hyperlinks, or making text bold or italicized, are not impacted by this bug. * Error has been replicated on OSX Yosemite, OSX El Capitan, and Windows 7 Enterprise --- SCREENSHOT DESCRIPTIONS * chrome_latest_noerror.png - Shows that the error does not take place on the latest version of Google Chrome * firefox_latest_error.png - Shows that the buttons vanish when the cursor is placed in the editable text area * firefox_latest_noclick.png - Shows that the buttons remain clickable in Firefox when the cursor is not placed in the editable area Image addition appears not to be working right now.
