Main problem is the user agent isn't per-site. There are several user agent switchers that work per site, and several that randomize, but im still looking for one that does both to actually fill the role.

From a "user agent tracking" perspective, random spoofing per site prevents user agent based tracking (though of course there are other methods) within a single session, without this feature it somewhat defeats the point as if you're on two sites within the same random cycle you'll still be user agent matched.

good product

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

Firefox 60.0.1 64Bit
Windows 10 Pro 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.

Does not remember the settings if "Synchronize between browsers" is on.

The author knows about the problem and promised to fix it.

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.

Возникла одна проблема. Включение настройки "Cкрывать настоящий User-Agent при определении средствами javascript (экспериментально)" ломает отображение картинок на некоторых сайтах (например aliexpress), при этом если добавить сайт в исключение проблема не решается пока не отключишь настройку полностью. Отключать ее не особо хочется. Можно ли это исправить?

P.S. При последующем запуске браузера проблема проявляется вновь даже если отключена соответствующая настройка. Помогает вк/выкл дополнения.

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

great！

Works like charm, keep it up!
