On 64 bit OS, In private mode, implement FileSystemAPI to store in memory
Lately I tried to download a large file from mega.nz using vivaldi in private mode.
I encountered some problems, and apparently there is a limit on the storage amount allowed in private mode.
Considering most machines today have a lot of RAM, I would suggest that on 64 bit OS, FileSystemAPI will be implement to store any data that should be written to the temporary cache/data store, so it would be saved into memory, and not to the disk.
