the URL to download
prompt user for a filename
Dowload a given URL to disk
This behaves mostly like downloadUrl, except that this function will use the native messenger in order to move the file to saveAs.
Note: this requires a native messenger >=0.1.9. Make sure to nativegate for this.
the URL to download
If beginning with a slash, this is the absolute path the document should be moved to. If the first character of the string is a tilda, it will be expanded to an absolute path to the user's home directory. If saveAs begins with any other character, it will be considered a path relative to where the native messenger binary is located (e.g. "$HOME/.local/share/tridactyl" on linux).
If true, overwrite the destination file, returns error code 1 otherwise if file exists
If true, cleans up temporary downloaded source file e.g. in $HOME/Downlods/downloaded.doc when the move operation fails e.g. due to target destination exists, OS error etc.
Download a given URL to disk
Normal URLs are downloaded normally. Data URLs are handled more carefully as it's not allowed in WebExt land to just call downloads.download() on them
