Maybe register for free with an email address or an account like facebook.
4shared probably still does not email you back to verify your registration; that is, if you do not plan to upload and don't care if the account could be hacked by whoever owns the fake email address you give.
If you use Firefox, there are a lot of great Add-On tools options, such as Ad-blockers, Youtube/video downloaders, etc, and an extension for MEGA which is supposed to prevent MEGA's downloads from cutting off.

I didn't find the right solution from the Internet.
