Not working anymore

Only works some of the time. Often just does nothing. When it works, it takes very long. Also required the container tab option to remain on, leaving the "open in new container tab" option in the right-click menu. Don't need container tabs or this anymore.

Works, but it's very slow, compared to other similar extensions that are much more fast to open the Google search page
