    I just purchased Spamfighter but the last release of Thnderbird has disabled my Spamfighter Toolbar: is there a Spamfighter toolbar compatible with Thunderbird 8.0 plz ?


  26. Jave says:

    Thunderbird 8.0 working well for me with SPAMFighter 7.3.70 on Win7 x64 Ultimate. (I did however have to go into “Add-Ons” and “re-enable” SPAMFighter after installation.)

  27. Hi Remi

    We’ve just released an update to SPAMfighter, that supports Thunderbird 8

    You can download the latest version here:

  28. Awesome, thanks for the updates Patrick!

    SPAMfighter working with Thunderbird 8 for me 🙂

  29. Digitaldude says:

    Spamfighter 7.3.78 FINALLY seems to work with T-bird 8.

    HOWEVER, it is STILL causing a T-bird memory leak. For the longest time I thought the problem of T-bird staying in memory after being closed was a t-bird issue. BUT I discovered the problem went away when Spamfighter did not remain compatible with T-Bird, and has now returned when in version 7.3.78.

    Please advise. We have been patient in your quest to get back in synch with T-bird development.

  30. Hi Digitaldude,

    Thanks for your question, i’ve never heard about that issue before, but I need you to write to our tech support department and tell them about the memory issue.

    You can contact them through this form:

  31. Patrick T. Rasmussen says:

    FYI: We’ve released a version that supports Mozilla Thunderbird 9. (Thank you Mozilla for releasing major updates all the time 🙂 )

  32. Thunderbird 6.0 is now supported by SPAMfighter – Finally!

    Great stuff SpamFighter!
