It is a nice plugin. I suppose the warnings exist due the shady host. Because once downloaded i feeded it to many viruscheckers, with no warnings as result. Can someone check that?
Because it is a nice plugin, i host this version on my own google drive. For everyone to try out.

X3M does not mind, till he has 500 reputation. Then this post will dissapear.
Best greetings.
I have checked this out some other virus checker does not show virus but, Norton, Bit-defender, Ashampoo, McAfee and AVG points out that it contain VIRUS
