Plugin is compromised, it's routing web traffic through a 3rd party affiliate tracker called magik.ly.

Mozilla needs to remove this plugin from the Add On market. Report it if you see the same behavior.

I was going crazy trying to figure out why if I was opening new tabs by right clicking links, around 1/10 of them would reload through "go.magik.ly" and bring me back to the homepage. It was this app, which is stealing affiliation links.

DO NOT USE. This extension forces your browser to reload on shopping websites, stealing affiliate commission and making companies think your browser is fraudulent / a bot. Several sites have now blocked my browser because of this. TERRIBLE APP DON'T USE.

It doesn't show up when I right click, it did immediately after I downloaded it, but as soon as I went to a different page to test it out, it was gone. Then I tried with hitting the button on the tool bar and chose an image, to pin, connected my pinterest account and it said that picture wouldn't connect. It then wouldn't even let me get back to the page I was on. What a bummer, I am a pinterest addict and was very excited for this. Uninstalling it right away as it does not work in any way whatsoever.
