Excellent performance.
Allowed me to download a Windows 10 iso (22H2) without using the Media Creation tool. I needed to use this tool because I needed to go from W7 32bit to W10 64 bit and the media creation tool only offered me the 32bit versions. By 'spoofing' my PC's identity to Android I was able to get the universal W10 64bit iso.

Excellent

work, but can't switch versions, also chorme is not update to latest version

Does not actually change the user agent

Clean interface, works for me to let me watch my Disney+ subscription on Linux.

Cette extension m'a permis de contourner le bug avec Disney+ qui ne fonctionne plus sous Linux, au week-end du 28 octobre 2022. Il suffit de sélectionner Windows pour contourner le bug

Some sites will not allow you to log in if enabled.

plug in works well. Allows me to do things on computer instead of phone.

Not work at detect website https://2ip.ru

site still recognize origenal OS and browser...

Continuously reports Firefox as version 56. It's not.

No switch back.
The extension works. It allows me to change the user agent, but for the whole browser. Not just the current tab.
On Teams, the messages suddenly got all scrambled. I had a mix of old messages in random order. Every refresh was giving a different set of old message. It's likely a bug at Microsoft, but still, that's not usable.
There is no way to revert back to the default user agent. I set it to my browser and OS, but Teams stop working saying my browser was not supported. I had to uninstall the app to continue using Teams.

I love this extension. I use it in both Firefox and Edge.

The only improvement that I wish the developer would make would be the visibility of the "DEFAULT" button to revert the user agent to the default setting. Instead of being hidden in the bottom row of icons, it should be a big green checkmark or something. Still a very useful extension !!

When returning to the default
[Are you sure you want to switch to the default user agent?]
Then, a confirmation dialog appeared and I could not return it unless I clicked [YES].

It is difficult to use due to the increased number of extra actions.

The dialog does not appear as before. Or issue a confirmation dialog, do not issue,
Wouldn't it be possible for the user to make a selection in the settings?

Thank you.

●「お使いのブラウザのバージョンは非対応です」と表示されて閲覧不可能なサイトでＵＡ偽装すると、閲覧可能になるので便利です。
●ポップアップメニューの文字列の右側が見切れますが、チェックを入れると問題は解消されました。
●可視性の問題。
「バッジテキストにＵＡを表示」にチェックした場合→「W/F」文字列＝黒、四角形＝暗いグレー
明暗差が小さいため、見にくい。
見やすい例：文字列＝白、四角形＝黒
●This is useful for sites that are not viewable because of the "Your browser version is not supported" message, but can be viewed by disguising the UA.
●The right side of the popup menu text is obscured, but checking the box fixed the problem.
●Visibility issues.
When "Show UA in badge text" is checked → "W/F" character string = black, rectangle = dark gray
Hard to see due to small difference between light and dark.
Easy to see example: character string= white, rectangle = black

Easy to use and configure and gives me some peace of mind.
