Really like this add-on and use it all the time but, for some unknown reason, recently has started to not work upon opening Firefox. Have to disable and then enable it for it to work.

２クリックでLINE、Twitter、メール、Mastodonなどあらゆるサービスに共有することができて使いやすいです。特に共有ボタンが設置されていないウェブサイトをシェアする際に役立っています。

Addon is good. Better share url for Telegram is directly to desktop App.
URL is:
tg://msg_url?url=https://www.firefox.com

parfait !

It really simplifies sharing a link to whatever services you prefer, all under one button. I'd envied the sharing feature on my Android phone, and this works better.

Tis is so helpful if you have multiple social media accounts.

thanks
