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

Unable to login TikTok website while spoofing Linux useragent on Windows.

Me ha presentado error con https://teams.live.com/_?utm_source=OfficeWeb#/unsupportedBrowser

Antes funcionaba perfecto

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 !!

●「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.
