Used this add-on in order to be able to download the Office 365 installer from Microsoft their site. Without the Windows user agent the download/install button would not show...

By default, sets a completely insane user agent, mixing up all browsers and os, making website believe I'm using chrome on windows

Seems ok but Edge browser is stuck on a very old version.
It would be nice to be able to enable (the agent switch) to a single tab

Tried installing it in firefox nightly on android, following the linked instructions. Can confirm it works! (But yes its quite a few weird steps to take) Thanks! ♥

The add on seems to work alright for the most part, but the domain override function doesn't seem to work. Every time I visit a site that needs human verification, I can't get past it even if I have the box checked. I have to go into my extensions list and disable the add on completely to get verified.

Override domain doesn't work- keeps reverting to default useragent despite wildcard domain set. Development seems inactive.

Worked great for YouTube, until they caught on and started blocking me (they showed the same default page "allow YouTube ads") anytime I had this set to Windows/Chrome :(

Good, but for example Edge browser is stuck on a very old version.

Definitely helped reduce the amount of problems with Youtube. Unfortunately, had to remove as it completely broke Google Docs. If you want to keep using, however, just setting the browser back to firefox fixes the issue.

suck it google, no more 5-6 second delay on youtube haha

This extension somehow break Google Docs' functionality, where it cause you to not be able to type anything in the document.

Needs an a dedicated on/off button, it blocks the cloudflare human verfication

Half works around youtube's illegal slowing of browsers. It loads faster, but the controls are still in slug-mode.
