Who is the host? от Brka OÜ

You can use this add-on to find who hosts a website. It is an official add-on for "Who Hosts This Site?" (https://whohosts.pro), and you can use it in two ways — from the context menu (right-click) for the current website or use the add-on popup to enter any URL.

Support staff commonly use this tool to determine the hosting company for a website. It also provides detailed DNS records for the given domain and a screenshot of the website's current state (taken once daily).
