I use mozilla for years, and now I had to reset my PC reinstall windows, and after that I changed pass for mozilla acc and I lost all my data, please help. I have instaled mozilla on android phone, but I lost it on one trip, and I'm expecting that returns to me, but I don't now when. So right now, I can't access to Mozilla acc and sinc date from other devices, but I will be able. Is there possibility to compare mac addresses from now and hours a go, so that I can have my data. Thanks for helping, it means everything to me.
