Still one of the best apps out there. It's a pity that the programmer cannot or doesn't want to develop the application further.

Great extension.
But there are a few things to note. Can you make the changed browser settings saved for the entire session and in all bookmarks?
You also need to add Font Fingerprint.

Fantastic on PC, but I'm severely annoyed that the geniuses at Mozilla aren't including this and more in Firefox for Android. According to Forbes, "...a company spokesperson replied: “Extensions can add powerful customization features to Firefox. However, we have noticed that the number of add-ons available for Firefox today can be overwhelming for some users."
Essentially saying, 'some of our users are too simple to make decisions, so we'll punish everyone for the few.'
Bite us all, Mozilla.

If it does what it says it does which it seems to do then it's the best Add-on EVER you could just use this one App I wish Firefox would recommend this thank-you to the author please keep it updated

Trace the new legend.
Can you please make "User Agent Customiser" with most recent versions? The webs now fight fingerprint protection by also requiring almost irrationally up-to-date browsers. Let's fake it with more recent versions.

Excellent!

Очень полезное расширение, спуфает почти всё, что может вас трекнуть. К сожалению, подмена Canvas отпечатка лично у меня не работает. Зато подмена аудио-отпечатка работает лучше, чем другие расширения. Почему-то ломается просмотр фото ВК и выбор доставки на Али.

WOW this is awesome! I tried it on several sites and it does what it says and more! Should be on Mozilla recommended extensions!
