... you should also in firefox deny third party cookies, e.g. those not for the site you are using, they are more commonly considered tracking cookies.
The thing with web bugs if you tried to block by domain it is a constantly moving target that you are shooting at, so the NoScript web bug saves constantly updating these domains.
I had a look at the FF Tools > Options > Privacy tab > and am pleased to confirm "Accept third-party cookies" was already unchecked my friend (makes a pleasant change to discover I actually had some of these damned settings right
)
On the NoScript thingummy, I've only been using that delightful program for about a month or so, but am too much of a dummy to know how to properly set the various options so had left it as it came.
I forgot to ask you if there's anything I should look out for that would ordinarily be safe and OK had Web Bugs not been checked/ticked?
@ Spirit and John please (or anyone else who'd like to shed light on this)
I looked at both SpywareBlaster and MVPS and it seems they provide protection via the browser only, whereas I'm certain I already have full protection by implementing FireFox's Privacy Options in conjunction with NoScript and a neat wee add-on called FlashBlock. I also have AdBlock Plus installed to kill any other nasties.
So, despite having opted-out yesterday of Yahoo web beacons and off network targeting (which I today checked were still disabled), I'm also fairly certain the path used by ad.yieldmanager to persistently return is via Yahoo Instant Messenger (YIM) and none of the above (including SpywareBlaster and MVPS) seem able to protect me via YIM which is why I asked in my OP if anything can be done via avast! Home. Or am I still being a dummy and one of them does protect from the YIM path?
I'm also thinking of making a complaint to Yahoo Customer Services because their opt-outs don't seem to cover YIM, but previous contact with them on other issues has been less than helpful.
What do you think guys? Can avast! Home (or something else) block ad.yieldmanager placement via YIM?
