Source code link still won't load

Notabug.org seems to be working, but if you right click the download button for the addon and click "save link as". It will give you an xpi that you can open like a zip file. The source code is there.

I do not know for sure if this is safe since it is not official. Original was made by gorhill --> https://github.com/gorhill/uBlock

uBlock origin is free software. Meaning anyone can modify it. I modified an old version that still works on SeaMonkey (modern versions do not), and updated it. And if your not sure if it's safe you can check the source code linked in the description.
