Finalement cette extensions est peu compatible avec Firefox sous Android. Bug au démarrage de Firefox pour le premier site lancé c'est l'UA par défaut ensuite c'est bon. Mais à chaque démarrage cela recommence...

excellentai dudes and dudettes

Works in Zen too! :)

Needed to use a site that was silently refusing to let Firefox users log in. Used this extension to tell the site I'm on Chrome. I can log in now. 10/10 Would recommend if you find a site that hates Firefox, this works to bypass it

The only user agent switcher I've found that reliably works. Allows you to apply custom user agent to a specific domain. UI is simple and easy to understand.

The best user agent switcher. Buffering on Youtube magically gone. Compared to using FF by default that YT will buffer every 10 seconds.

very good at its purpose
