It breaks cloudflare challenge. You have to blacklist every site that uses cloudflare to avoid this issue

Not sure if I am the only one but when I use this soundcloud gives me an error, but other then that it works like a charm

Awesome way to bypass anti-trust artificial slowdowns by competing platforms. This addon should be classed as a top-priority must-have privacy app.

Does not work for me on https://webbrowsertools.com

All those websites with cloudfare security cant be accessed with this addon enabled. Wasted hours of time searching for the reason.

Works like a magic. Thanks a lot!

For those websites that "OnLy WoRk In ChRoMe" but actually work just fine in firefox, this will save your life

▶️ Very Good Plugin User-Agent Switcher and Managerот Ray ;)

N'affiche pas le bouton en firefox 117.0 et donc impossible à utiliser...

Cloudflare, which vast majority of the U.S. sites and 20% of the world's websites use, does not like this app. Also, you ID is simply revealed by the http software you are using. Hence your ID will show as being faked.

Does not work – user agent stays the same.
