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.

It works. It works well BUT it floods ADs, some precede videos in sites - bombarded with useless, bogus ads - SHOVING them. As much as I like being able to easily present a browser change, the issue still remains.
