Me gusta su eficacia para compartir una frase seleccionada de cualquier artículo que estoy leyendo, con total simplicidad de recursos. No lo modificaría en nada.

skip redirct と競合するのでskip redirect側で対処が必要そう。
It'll compete with the addon "skip redirect"

firefoxではトラッキングブロックが内蔵されているため、その影響で共有ボタンが表示されません。
こちらのアドオンで簡単に共有できますし、タイトルも含む共有ボタンを表示してくれます。

Tracking blocker is included in firefox, but it has effect on sharing button.
With this add-on, I can easily share on twitter. The tweet also includes the title of the page, not only the URL.

To be perfect you should have the option of setting up a keyboard shortcut.

Bella impostata bene ma ... non scorre la pagina e non segnala le notifiche con pop-up o altro quindi a me risulta molto macchinosa

simple & quick

Very good app. Very simple and user-friendly app to quickly and efficiently post links to Twitter.

Great add on wish I had found it sooner. It works much better than the official Twitter one I used to have.

Thank you.

Fx 工具栏上必备3大神器：
1）diigo 。mark 、收藏页面，用标签管理，便于日后检索。代替之前著名的delicious（似乎在雅虎下处于等死状态）；
2）crip to evernote。对于重要的网页文档，建议保存到Evernote ;
3）share on twitter 。分享当前页面到推特。

Great extension, simples and very efficient.

I will give 5 stars when it get the same color scheme as the native Firefox extensions

Have been using this for some years now, recently it became unstable, however the with the new update all looks well.

Otherwise, excellent app, makes life easy for me in the way I use twitter to quickly keep/share links.

it has been a lot better way to share something on twitter than FireFox's bundled share button.

But I have to say: recent update added option "open sharing link in with default value=new window" was a bad idea. it messes up in the same way as "share button".
