I have a Firefox extension need to write to one files inside the extension’s chrome folder, it works fine on windows and linux, but it give me 0x800520015 NS_ERROR_FILE_ACCESS_DENIED error. it is very strange, I manually set the file to have write permission, it works fine then.
My question is where should I set something to tell MAC OS to give write permission to that file.
Thanks.
Which “chrome” folder (post the path)? If you’re talking about application’s chrome folder, it’s a bad idea to write there; newer Windows will not let you do that either.
[edit] so if it’s in the extension, you may have the wrong permissions set in your XPI file accidentally. You can change the permissions from your extension (see
nsIFile.permissions) or create a proper ZIP while packaging. (Can you post the ZIP file to verify?)Anyway, why do you want to write to extension’s folder? It’s usually a bad idea.
