I use Firefox and ublock, and usually it lets me download a couple of files before the ad wall kicks in. I too am irritated by the arrogant "let's play fair" nonsense and find some ads objectionable. I'm also concerned about malware because they obviously are so indiscriminate with their advertisers. So I will switch off the ad blocker only if I get the ad wall on an item I really want, and just to reload that page. "Fair" compromise I think.

That seems to be correct.I think you can let ublock active while downloading files that are under the 100MB limit.
