XULRunner Ignores Updates On Edited Files

I am writing a XUL application following the default structure for standalone XUL apps - that is, I have the following files: ./application.ini ./chrome ./chrome/chrome.manifest ./

Solution 1:

Yes, there is a XUL cache. To disable it you can add nglayout.debug.disable_xul_cache preference and set it to true. You can also run XULRunner with -purgecaches command line flag, this will clear XUL cache and all other caches as well (relevant once you move on to JavaScript modules or XPCOM components).
