this is the best user-agent addon.
it has all the features you need.
best of all it is well put together and incredibly smooth.

good product

Somehow this addon will cause Twitter's input box stop working (can not cut or paste).

Firefox 60.0.1 64Bit

Klein und funktioniert top! Einstellungen sind ebenfalls top! Vielen Dank!

Does the job well and the best random user agent switcher I found so far. Consider adding Chrome for Android so that there can be a few versions (latest and some early versions of chrome for mobile) of that user agent, the more the better. Consider keeping the user agents updated and more randomized from time to time so that websites do not blacklist certain user-agents. Overall I see great potential in your add on and hope you keep it updated for a long time and keep it growing with functions.

Great job -- minimal and effective. Thank you for developing this.

Works great! You need to add user agents for several Android browsers, everything else works fine.

Works as expected, easy to use: install and forget. Been using it for months, don't plan to stop using it.

a list with regex->specific UA could be a good addition

Работает без проблем , хотелось бы более расширенные функции , к примеру , как у Random agent spoofer.

It works great

De loin, d'après mes tests, la meilleure extension de gestion de l'en-tête anonymisé User-Agent, qui est absolument nécessaire pour un peu de vie privée.
J'ai également sollicité le support sur un problème étrange, qui s'est avéré ne pas provenir de l'extension, mais de ma configuration pré-existante. J'ai reçu des réponses très pertinentes en très peu de temps et ai pu régler mon problème.

Bonne alternative pour changer le "user-agent" régulièrement.

great！

Works like charm, keep it up!
