really helps me with work

Works perfectly. I can access subscription based forums with this :D

Jaj cool

Please, add other browsers, yandex, opera ...etc.

in my case it doesn't help. on some particularly "especially smart" sites (in mobile versions of which, for example, the capabilities are limited), when choosing the user agent windows, it still says that I’m logging in from my phone.

Lo use para que el navegador de mi tableta muestre las páginas como un navegador de escritorio. Asi provecho mejor la pantalla, y tengo todas las funciones de escritorio

Causes a gigantic memory leak.

I never remembered downloading it I guess support did. It BLOCKED me from doing something(for me specifically it was the CloudFlare human verification). Only after troubleshooting FireFox and removing everything but it and adblock did I finally remove it and the problem was solved instantly. So if you are having problems with something and this is on the browser remove it and I believe unless it is an actual error it'll solve it for you.

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! ♥
