@gendofr 90% of the time, there's nothing wrong. Reaching your full internet speed when downloading something from a web site will always be an exception, since most sites limit the download speed.
Opera can't recover deleted download lists, but the downloaded files themselves might still be in your default download folder. File recovery software might work if you recently cleared the list and haven't downloaded anything new. Enable download history in Opera settings to avoid this in the future.
@leocg Thank you for this! I thought I was losing my mind. Just as the original poster stated, there was simply no activity after clicking subsequent download links. I enabled automatic downloads and all is well.
I am new user of Opera browser and I love it, but I really missing this feature that is available for all other browsers I have been using. It will be great if it can be added at some point.
