cache remote pac files on harddrive instead of loading it everytime upon starting

Hi, thanks for this excellent extension, it makes my life much easier^_^ FoxyProxy is configured to load a large size pac file remotely, but it makes Firefox startup's time much longer than using a local pac file. So I think is it possible to cache the pac file on local drive and download/reload it after ff has started? But I know little about coding, stop me if I make spam. Best regards

local pac file

 
Where do you load the PAC file from now? Or why can't you store the file locally and configure FoxyProxy to work with it?

Indeed, you can save the PAC

Indeed, you can save the PAC file locally and use file:// to point to it on your hard drive instead of http://
