There is necessary to restart application after you change IE compatibility (PSPad program settings / System integration) - Windows limit. To display content in Chrome or FF you need to include their engine - you can't use browsers directly. In the past there were MozillaX Control (obsolete now), there is an Chromium SDK (about 200MB). You can use external application (Highlighter settings / HTML) to open your web page in different browsers - it's simplest way how to do it.
