Dear Sir or Madam, we have had a major problem with Firefox since today! Our specially programmed software, which displays HTML 4/5 with onClick and forms and submit, has stopped working since today! We can no longer work properly! Example: We click on a button with onClick, an input form is created, e.g. for a construction site with Jquery query and submit button (OK up to this point) and then another input field opens, e.g. for entering hours, and we enter a number/value. - From this point onwards, you can no longer press Enter on the keyboard and there is no (Submit) button in the form to click on. So from the second form controlled via IFrames onwards, clicking is no longer possible!!! It is affecting more and more users who use Firefox! Please check urgently.
