I have been having this problem for some time now with a few apparently random javascript source files. Tonight, I finally had enough and decided to investigate. After reading messages in this thread, I upgraded my Firebug to 1.4x.0a12. To no avail: problem remained.
FInally, I found out what was wrong. My web page uses UTF8 encoding, and so do all related files (PHP, JS, etc). The ones that did not load in firebug were the ones that were accidentally saved with ISO8859 encoding. Your problem may be different, but using encoding consistent with the web page solved the problem for me. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Firebug" group.
