Hello, Simple question: i have firefox on my phone and on my pc, and i have currently "a lot" of tabs opened on my phone for work, and i would like to have those pages saved somewhere in order to have them on my pc. However now i have to change my phone and the old one will be given to my friend, and obviously i have to reset it. Now, those tabs openned on my phone, when i reset it, will be deleted from the sync? I must mark them as "favourite" or as "bookmark" in order to save them everywhere?
