Ich wünsche mir die Option zu Syncen & zu "Merge Data"

I love this add on because it protects my searches from Facebook trackers. I love it!!!

Seria possível criar uma extensão semelhante para a rede social Twitter?

Does exactly what it is supposed to do. Knowing then what I know now, I would have never signed up for facebook.

It works well. I also recommend Firefox Multi-Account Container Addon by Mozilla.

Excelente, recomendada 👍

Great protection of Facebook's horrible privacy-breaches. It gives subtle warnings about where and how Facebook is tracking you and contains (most of) it, without getting in the way of your browsing experience.
