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

OK

It's exactly what I was hoping for. Thank you!

You just need to search for a new configuration json file on github gist and import it.
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

Useful! But Google's API seems changed, so hope the author will update this addon.

doesn't work, opens an empty window

Works flawlessly, except when you open a second window, in that case, if the search opens in a new tab, it doesn't matter if the setting is "next to current", the new tabs always opens rightmost of everything.
This only affects a new window, searches in the first main window behave correctly
