That adblocker does not sound very effective

No popups when using uBlock Origin and/or uMatrix

   scheme=https://
   host=simpleflying.com
   ip=34.233.113.241
   path=/united-airlines-767-returns-newark-bluetooth-name-alert/
   {
   echo url=$scheme$host$path
   echo output=/dev/stdout
   } \
   |curl --resolve $host:443:$ip -K/dev/stdin \
   |sed 's/<img src=[^>]*>//;/user-comment/,$d' \
   |grep -o "<p>.*</p>" > 1.htm
   firefox ./1.htm
   #links -dump 1.htm

The real "nightmare" is the browser that will automatically run all that garbage returned in the response body without any input from the user

It requires an "adblocker" to stop its default behaviour

Alternatively, one needs to disable Javascript, restrict the browser's access to DNS, etc.

When an advertising company releases a "browser" that intentionally allows website operators to cram pages fuil of advertising and tracking is that a coincidence

Is that the only way a browser can be designed

No

How many users realise this

A small number

For example, I'm using a browser that cannot automatically request resources, run Javascript, CSS, etc. where HTTP headers, including cookies, are trivial for the user to create, edit, save and delete. I do not need an "adblocker"

"Don't these sites realise how many users they're losing?"

The number is so small why would they care
