Thanks to Adblock, there are hardly any such annoyances in
Firefox. Without having to know anything about the target
website.
Filters will vary in multiple levels of firewalls, routers, logistics
for blocking possibly whole countries. Problem with unique FF
extensions is pairing them to version that don't puke, devolving
regressively into FF's Achilles Heel, memory leaks. ExtEMM is one
that helps - restarts the tab sessions more or less successfully
according to browser shutdown preferences - periodically stuffing the
pig hole in FF's runaway memory issues. Big Brother's bother setting
it up with 15 or 20 extensions for customization levels, Opera won't
come near. Problem is, with these newer sites, the big ones, nothing
readily can be accomplished with FF. So, its back to Opera to order a
bag of peanuts from Wallyworld. Even with Opera, there's apt to be
issues. For one, mass obscenity. Tried Yahoo lately with an updated
IE ... a regular 3-ring circus for intrusive hacker scripts, to wider
levels of accepted competence for advertisers to practice a sort of
reverse engineered porn for kids.
