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.
