You've probably used "View Source" in Firefox. You can have Microsoft Word be your application to view source. This is a read-only copy that you would have to save into a new location; you can't actually edit the live web site using Word through Firefox. There might be an add-on to make this easier, but if not, here's what you need to do. First, you need to get the path to Microsoft Word 2003. On XP, this probably is the following: '''C:\Program Files\Microsoft Office\OFFICE11\WINWORD.EXE''' You might want to select that and copy it to the clipboard. Second, you need to update two settings in Firefox. (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful. (2) In the filter box, type or paste '''view_source''' and pause while the list is filtered (3) Double-click '''view_source.editor.path''' and paste the path to Word. (4) Double-click '''view_source.editor.external''' to toggle it to true (it should turn bold). Then return to a regular web page and try View Source. Does it work? One issue you may run into is that by default, Word will render the HTML source back into a web page. To defeat that, you may need to set this option in Word: Tools > Options > General tab > ''check'' Confirm conversion at open Then choose Plain Text when prompted. Hope this helps.
