Not sure how to install an AdBlocker

Hi - Kind of a "first time user" as I've just gotten by 1.67GHz PowerBook down from the attic after a long hiatus :) This is therefore a newbie question - I apologise in advance :)

I've just installed PR3, but when I tried to install AdBlock Plus (the latest build, adblock_plus-2.9.1-an+fx+sm+tb.xpi), I'm getting the message "Adblock Plus is incompatible with TenFourFox 45.12.0". I don't have to run Adblock Plus - just wanting an adblocker that works well working under Adblock Plus.

Any suggestions would be welcome :)

Thank you, Patrick

    Congrats to your new top-of-the-line PowerBook :-)

    Go to

    Then scroll down to the Version Information, click "see complete version history" and install an earlier version of the add-on, e.g. v2.8.2.

    Or you could pretend to be on Firefox 52 (Preferences>TenFourFox>User Agent) and see if it installs (may not work).

    BTW I use uBlock, it's considerably more light-weight than Adblock Plus, but not as easy to use.
