bruh? this extention has some problems with playing video from Youtube!!!

Excellent switcher with easy selection of browser/os and easy updating of User Agent string. Much easier than accessing about:config.

Unlike other user agent switcher, this one lets you switch on per-site basis!

Chromeでないと弾かれてしまうウェブサイト及びウェブサイト内のコンテンツの再生時にとても重宝します。

特に使いにくい感じも見受けられないですし、使う頻度こそ少ないですが、大変重宝するアドオンです。

This is awesome and way better than another user agent switcher extension I tried which gave only very few user agents. This one provides linux ones, for instance. I spoofed MS Teams to do a working video call through firefox on linux which is even better than their electron-based client since that only allows you to see a 2x2 grid of people, while in Chrome (or firefox with chrome UA) you can see way more. Nice!

Best agent switcher out there !
