It sounds as though your compiler or other tool for making an XPI needs to be updated.
I could only find one that worked but I don't think it's been updated in years. Are there any other tools out there?

I'm not aware of any modern compilers (i.e., ones that work with the new Add-on SDK). Any reason you prefer an XPI to a userscript?
To install a userscript you need to have greasemonkey installed from what I have tried. If there is a way around this then I could work with it. It would be simpler just to install the XPI file
Firefox 32+ compatibility
Hi,
I've created a GreaseMonkey script which runs fine. But when I convert it to an xpi file on firefox version 32 and higher it gives the following error, “XrayWrapper denied access to property onload (reason: value is callable)”.
I've tried running the same xpi file in older versions and it works fine.
Any help would be great,
Thanks
