Dear Mozilla Team, I hope you're doing well. I have a question because I am not sure about things how works when someone changes a device. 3 days ago I changed my Mac device to a new one and however I logged in with my profile my Mozilla Firefox looks completely different and I would like to know which version I used let's say a week ago and what is the version now, is there a way to figure out this? Honestly, I don't like this version and I would like to get back the old one or the old customization. Can you check this for me please? Thank you, Richard.
