In case you were curious as to where you had heard the name Christopher Soghoian before, he was infamously raided by the FBI in 2006 for posting information about airport security that allegedly jeopardized homeland security. Hence the odd photo of him on his site in orange overalls being rubber-gloved by an officer of the law, presumably.

For a quick run through of removing Firefox addons check out this post. And, if you want to be really secure, disconnect your internet connection and uninstall Firefox altogether and maybe taking up gardening instead.

    By the way, if you run your Windows machine under a limited user account to help protect you from malicious installs, then don¡¯t think you are safe from this exploit in Firefox. Firefox will update and install addons regardless of the status of the logged in user (a bit of a bummer in terms of security, really).

  • Wayne Smallman // Jun 5, 2007 at 8:16 pm

    ¡°This possibility exists whenever the user cannot trust their domain name server (DNS) or network connection. Examples of this include public wireless networks, and users connected to compromised home routers,” says Soghoian¡¦¡±

    As you mention, the implications here are immense. Quite sobering, in fact.

    Good job I¡¯m on OpenDNS, as well.

    Additionally, this could be the very tip of a whole new class of Internet fraud¡¦

    Yep, readers should check out the review of OpenDNS on this site and Wayne¡¯s earlier review of OpenDNS

    UGH. Another thing to worry about. The other day, I went to a site I visit frequently and my Google Desktop told me there was potential malware on it. Turned out it was one of the ads being served and probably only to users in W. Europe and Asia. @#!

  • David Bradley // Jun 6, 2007 at 10:53 am

    It is the way of the world Hsien, I¡¯m afraid. Even more bad news from Poland via zdnet yesterday - apparently numerous security holes have been opened up in the fully patched versions of Internet Explorer and Firefox.

  • Tom // Jun 6, 2007 at 12:20 pm

    Rumors abound that Firefox 3 will have an antimalicious streak.

    Fuzzers poke at programs in search of vulnerabilities that can arise when an application receives data it doesn¡¯t expect. Now, Mozilla (producers of Firefox) are unleashing these hacker tools on to the net in the hope that the community will spot security loopholes before hackers/crackers and alert other users and Mozilla itself before such problems become serious.

    1) how can firefox addons be DELETED?

    2) why does all typing, now, since the installation of firefox show a series of small red dots under everything in email?

    3) this new install has taken over everything - 40% of the screen =- and is a nuisance!

  • David Bradley // Aug 24, 2007 at 8:35 am

    mack, removing firefox addons is relatively easy. go into the Tools menu, slide down the menu and click Addons. A box will appear with those you have installed. Simply select the ones you no longer which to run and hit the Uninstall button. Restart FF and they will be gone.

    As to the red dots¡¦are they spelling errors?

    To what new install are you referring? The latest version of Firefox or an Addon? Have you tried cascading or tiling your windows from the toolbar (assuming you¡¯re on XP) and then resizing them to your preference?
