When I visit some pages and I usually press the back button fast on my mouse to get back to the start page in Firefox. And that creates a empty html file in my downloads folder with a random name. The only extension I have is ColorZilla. And I have 2 plugins: * OpenH264 Video Codec provided by Cisco Systems, Inc. * Widevine Content Decryption Module provided by Google Inc. I'm using Firefox 122.0 on Windows, and it's been like this for as long as I remember, so at least a year. I never fiddle with anything in the browser so everything is like default installation besides the plugins and extension. It usually happens when I'm on an ad heavy site and then spam the back button fast to get to the start page, and that's when that download popup shows some random file generated in Downloads. I can't recreate the issue now when trying, but it usually happens now and then. I don't have any ad blockers, but I suspect that it might have to do with some ad not finished loading or something like that. I'll attach a picture of my downloads folder. I usually just browse the web for like 2-4 hours a day, so you see it created quite a few files for one day.
