I can only suggest that you've somehow managed to accidentally disable AdBlock for the site. Is the AdBlock icon red or green when you're on the site? Some of those ads are totallly vanilla Google Adsense, so if those were getting past Adblock then you'd be seeing them everywhere.

I think some web browsers, under pressure from advertisers/corporates (especially major software firms) are making life difficult for small independent software writers by continually changing their software so add-ons aren't compatible or work poorly.

I gave up on MS browsers more than 5 years ago and now mainly (95% of the time) use Firefox (not perfect, but still has the most add-ons available) and sometimes Chrome when Firefox doesn't work so well on some sites.

I also use uBlock origin (a lighter-use product than AdBlock Plus), AdGuard AdBlocker (to catch some bits like pop-unders that uBlock doesn't) and Ghostery to get rid of the annoying ads, especially the 'moving picture'/Flash type ones that do slow down computers, especially older ones and particularly tablets with less powerful graphics processors and memory. My Galaxy Tab3 wouldn't be able to function on this website and especially the Telegraph if the above weren't installed.
