User-Agent Switcher and Manager
Spoof websites trying to gather information about your web navigation—like your browser type and operating system—to deliver distinct content you may not want.
User-Agent Switcher and Manager: Customize Your Browser Identity
'User-Agent Switcher and Manager' is a Firefox extension that facilitates privacy and customization of user experience. It allows you to alter your browser's 'user-agent' string, making it difficult for websites to gather specifics about your browsing setup. This tool is particularly handy for controlling the content that websites deliver to you, based on your apparent operating system or device type. From accelerating loading speeds by indicating a mobile device, to improving privacy by randomizing your user-agent string, this add-on is a powerful tool for modern internet users.

Literal god-send. On Linux trying to get Windows .iso files for VM and because I'm on a desktop computer Microsoft in it's infinite need to control users does not allow the download of .iso files or even make it an option... unless you change the user-agent of course, then it's not a problem any longer. Saved me having to actually use my phone to do it again like last time. Nice work people!
