I use adblock plus (notice a trend here?) and I formerly used tampermonkey. It doesn't work right, and the scripts I liked aren't being updated, so I quit with it. If there was a DownThemAll! add-on for chrome, I would most certainly use it. The ability to download from multiple mirrors is really useful on large files. It even supports MD5 checking and auto restart if it fails.
