Could be the best UA changer out there if it worked. Something broke or there are unknown conflicts (Multi-Account Containers?). Some other extensions of this kind I tried also don't work.

So-so. When it works very good, but often randomly does not work and then i have re-install, switching on-off etc... Unreliable operation ...

Extensão boa, mas que precisa melhorar a resolução de tela da interface de configuração no Firefox para android e se possível aumentar e atualizar a lista agentes de navegação.

Well thought-through simple user-friendly interface. There are some issues with it interfering with the functionality of some Web sites (e.g. LinkedIn). I'm not sure why that's the case. If it wasn't for this, it would be a great add-on.
