I am at my wit's end with this. checked every single post on every website but nothing works. anything larger than 30 megabytes always fails in the middle and I have to keep resuming it. It also keeps giving me the same error message "Downloads\example.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator." I have tried safe mode. I tried changing the download location, it still tells me that the .part file in the Downloads folder can't be read. This .part problem started recently after a firefox update for me. But the downloads getting cancelled for no apparent reason has been a forever problem. Is switching back to Chrome the only real solution? (I've been told this)
