No colored boxes to select when creating selectors to scrape

First time using WebScraper on Chrome.
After creating a new sitemap, I proceed to create the selector to scrape.
But after choosing for example "Links"-> "Select"-> and then browsing on the page with the mouse, there is no green/red boxes appearing on the website, and I am not able to select anything.

How shall I proceed?
Thank you :slight_smile:

@lili Hi. Please, make sure that the 'toggle device toolbar' option is not selected. Also, it is possible that the data you are after is embedded into an iframe.
