[NTLUG:Discuss] Netscape Quality Checker or something like that

[Leroy Tennison]

I downloaded Firefox and Thunderbird recently and began using them.  
Tonight this Netscape Quality thing popped up for no apparent reason.  
It supposedly offered the opportunity to cancel but not only was that 
conveniently grayed out, I couldn't kill it by clicking the X or 
File->Exit.  Fortunately the KDE ProcessTable application was able to 
kill the 'talkback' process.  I found two 'talkback' executables: 
/opt/firefox/extensions/talkback at mozilla.org/components/talkback and 
/opt/thunderbird/extensions/talkback at mozilla.org/components/talkback (it 
did pop up a second time a very short while after the first instance).  
What I'm wondering now is if I have Spyware installed.  Anybody know 
what this is and whether it's harmful.  If not I'm seriously thinking 
about looking into configuring IPTables to block outbound transmissions 
to Mozilla.org and fullcirclesoftware.com.
