bueno, pero con carencias. Rated 3 out of 5 stars

Buen complemento, pero falla en que hay que añadir los agentes de usuario a mano y que no funciona con el agente de usuario de JavaScript. Hay otros complementos que sí permiten mantener la privacidad en el AU de JavaScript, pero lo ideal sería que sólo hiciera falta un complemento que se encargase de todo ello.

This add-on works well and gets the job done, without having to restart the browser like other, older extensions. It is an essential add-on now that site-specific user agent overrides have been removed from Firefox.

It really needs a list of pre-defined user agents so I don't have to go hunting for them to copy-paste each time. It could even automatically import the list from User Agent Switcher:

It would also be nice if it could integrate the functionality of User-Agent JS Fixer so that two separate extensions were not required.

Thank you

If one day I have some time, I may just integrate the code from "User-Agent JS Fixer" (or I could change the license of ua-site-switch from GPL to MPL, so the author of "User-Agent JS Fixer" can integrate my code into his add-on).
Also proposing pre-defined user agents would be indeed nice, but for the moment the lack of motivation and time prevents me to do it.
Thank you for your feed back!
