To the authors Rated 4 out of 5 stars
Very good idea to begin with: cross-site media downloading.
Very easy user interface and fairly obvious controls.
there is this one issue. Whenever a file is downloaded, the extension alerts the download path for no rhyme or reason. Then the confirmation pops up. The first alert shouldn't be.
I fixed it by editing the core.js file, line 266 by commenting out the alert func.
I hope this and minor spelling mistakes are rectified in the final release.
I am willing to help with minor things if the authors wish.
