Both for a converted xul and bootstrap addon (which are working after conversion), addons -> debug leads to a page where the debugger-sources tree says: Seite enthält keine Quellen (page contains no sources?). (using extra-> developer tools->dbug addon)
Using the developer toolbox, I get a list of js pages in the debugger but didn’t find mine. There are two moz-extensions, but they are not mine.
All that never was a problem in TB60. Any help is appreciated.
