I want to close the current browser, open a new one and let it continue it's work. It looks something like this:
browser = Watir::Browser.new :chrome
.....
browser = browser.close
browser = browser.new
..
But after closing the browser it returns
uninitialized constant Browser (NameError)
Thanks :)
when you call browser.close, the browser object gets removed after the actual browser is closed. To make a new one you need to use the same syntax you did the first time (as indicated by Justin in the comments to your question)
browser = Watir::Browser.new :chrome
