New Comer asking for help

My first time using the web scraper. Why am I getting this message when I click on app icon

Open Developer tools where you will find Web Scraper tab:

Windows, Linux: Ctrl+Shift+I or F12
Mac: Cmd+Opt+I
Any OS: open Tools / Developer tools
Documentation is available on webscraper.io

Open Developer Tools (For Chrome: Control+Shift+I) and there you will find a TAB for Web Scrapper. Good Luck

Thanks a lot. I appreciate
