Hello, I have an issue in Firefox browser. My operating system is the latest version of Kali Linux, and I am using Firefox ESR version 128.5.0esr Also, I don’t have any extensions installed on my browser, and the default theme is active.

Sometimes, an empty HTML file with a random name, such as LmFPlKJM.html, gets downloaded. This has happened to me twice so far. Both times, it happened while I was on a website that I had configured the server for. However, I didn’t do anything on the page; suddenly, I saw that the file was downloaded. I wanted to check the download link for these files, so I right-clicked and clicked "Copy Link" in the download tab, but the link showed as about:blank. Can you guide me on what this issue might be? Is it dangerous?
