Cons
Con Just a browser addon
It is just a browser addon so it will only work with the supported browsers and you have to install it for all browsers separately.
Con Element hiding helper has occasional hiccups.
Con Memory hog that gets worse the longer it runs
Happened with 64-Bit Firefox 62.0.3 running on Desktop PC with 64-Bit Windows 10 Pro with 8GB of RAM.
Con Slow
Like any browser extension it slows down your browser.
Con Needs root (by design)
Needs root to update the hosts file.
Con Won't block same domain ads
Because the host file can only redirect domains, if the ad and content are on the same domain the ad will be displayed.
