I'm hoping a developer for Firefox sees this: With as much technology existing today, I think it's a big miss that "Collections" aren't synced across devices. You spend a couple years setting up an amazing Collections resource, and then you get a new device and have no efficient way to retain those collections. The idea that I have to open every link, copy it, text it to myself, open it on the new device and save it into a Collection again -- for every single webpage I've saved for years -- is nauseating. Is this something that developers could possibly work on improving? I'm not even interested in building Collections again, considering that they are just a temporary, device-specific feature. Why bother, if I'm just going to lose them every time I upgrade my device?
