Not sure what forum to post this in but I thought because it's in some ways related to security (i.e. a bad download site would result in security issues). If wrong forum, I apologize.
I understand the desire to use the vendor's own site for download, but as you know, sometimes this is not possible. In that case, what is/are your preferred download site(s)?
I know that my uBlock Origin extension blocks "download.cnet.com" ("cnet.com") and from what I've read in the past, probably for good reason.
