完全不知道怎么用。

Great extension, ignore below PS, to dev: Do you have a public repo for this? Would like to try and fix an issue with the extension handling urls that only appear to be postscript files (e.g. just had to disable the extension to view a github repository page: https://github.com/idavis/prototype.ps)
