I was assigned the task of creating a simple website that opens links to other websites. However, I encountered a challenge with one particular website, which was built in 2012 and follows outdated standards. Ideally, I would rewrite it to meet modern standards, but unfortunately, I don't currently have access to the source code. Therefore, this becomes my plan B.
The issue with this website is that it is only compatible with Firefox due to its outdated design. My goal is to make my website detect the client's browser and, if it's not Firefox (e.g., Chrome), automatically open Firefox and direct the user to the link of this outdated site.
I have conducted research and discovered that achieving this task is generally considered impossible. However, since this website will not be public and security is not a major concern, I'm willing to explore alternative approaches.
