@n4i75irhc1371 but it should one day soon right? how hard can it be to map a to b? slightly trickier than bookmarks, but not much. can it open all open tabs into respective window groups on new machine like chrome can? that seems 2% tougher.
I have bought an additional external drive, now I don`t experience the problem. Seems like Windows automatically deletes some crucial files when there is no or low space on system drive C.
