Hi Ian, I don't think there's a straight forward way to do that regardless of the browser. Unlike native app that has a clear update notice, it's not always noticeable when a website was updated. A blog-type website may be more obvious because you can see from the last update date, however for most other websites, you can't really tell when it was last updated. You may want to search in a search engine of your choice to look for alternative ways to do that. For your information, this forum is intended to help users with Mozilla products, such as Firefox.
