I was working in a plunker (an online HTML javascript demo-hosting site), and I wanted to download my work as a .zip file. I took the following actions:
1. Tried to download my work in a .zip file.
2. Chrome raised an alert in my download bar saying that the .zip file "may harm [my] browsing experience, so Chrome has block it."
3. I noticed that a file called `Unconfirmed 158006.crdownload` was actually added in my Downloads folder.
4. I renamed the file with a .zip extension (since I was expecting one)
