Works fine except for the Google option, it doesn't work

OK

For example, "llc0930" is my username, and I only put one file there...

Used this a lot on Chrome was glad to see there is also a Firefox version. No longer do I need to comment on someones post saying "Source" knowing that its not their art to begin with xD

doesn't work, opens an empty window
