ad blocker
/æd ˈblɒkər/
Very CommonBrowser software that filters out ads, trackers, and other unwanted content from web pages.
The morality of using one is debated: publishers argue it kills their revenue, users argue it is self-defense against privacy invasion and malware. Both are right.

Origin and context
Browser-based ad blocking existed in various forms since the early 2000s. Mainstream adoption accelerated after AdBlock launched in 2009 and uBlock Origin in 2014. The practice became widespread enough that major platforms began actively detecting and countering it by the mid-2010s.
