    Prism support? Simply awesome


  2. Gail · 2009-10-12 21:57 · #

    Is there a version of Adblock Plus that will install in the Linux version of Prism?
    Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv: Gecko/2009090217 prism/0.8

    Attempting to install gives an error that Prism is an incompatible version.

    I would really really like to get Adblock Plus to work with this version of Prism for Linux but don’t know how to do that. This is the most up to date version of Prism available in the software repositories.

    Reply from Wladimir Palant:

    This has nothing to do with Linux – Prism 0.8 is pretty outdated and no longer supported. I can only suggest you get Prism 1.0b1 from (1.0b2 isn’t available for Linux for some reason).

    Thanks for the reply Wladimir.

    I messed around with the release candidate of Prism for Linux (1.01b.1) and it definitely has issues on my computer. I cannot get a Prism app to run with a status bar which is what it takes to install Adblock Plus or any addon for that matter.

    I really wish that Linux wasn’t at the bottom of everybody’s priority list for updates in everything, but that is a simple fact of how the Linux world works.

    Sorry about the rant, no fault of yours of course and Adblock Plus has worked absolutely beautifully in every platform I have ever installed it in.

    Thanks again, for the reply and for the excellent work you’ve done with this addon.
