Most tabbed browsers allow opening pages in a new tab. At a previous job I used https://github.com/mbhutton/chrome-duplicate-tab-detector https://github.com/mbhutton/chrome-duplicate-tab-detector ( http://chriswarbo.net/git/chrome-duplicate-tab-detector http://chriswarbo.net/git/chrome-duplicate-tab-detector ) for chrome, which was useful for switching to URLs from other programs (e.g. if a Web site's integration test failed, the error message would include a URL to see what (unexpected) output was found)
