  • not available fo tb..
  • It is not supported on firefox 27. Will it be updated?
  • For firefox 16.x. Here's how:
    1. Download the .xpi file to your computer.
    2. The .xpi is a file like a .zip, Open it using a zip application like 7zip.com.
    3. Edit the install.rdf file and change the max version to 16.0.*
    4. Save, and then open with firefox to install.

    I have contacted the developer to fix the above but his email address is bouncing back. I prefer CSS viewer than anything else found as CSS viewer coz it's lightweight and works like a charm without any other heavy features that a non-developer guy doesnt really need. Kudos!
  • Update please not work in ff16
  • The CSSViewer 1.0.5 fix by camilog works great in version 12! Thanks so much!!!
  • I love this plugin when it works... Unfortunately it usually takes several weeks to update after an update in Firefox.
  • great tool to simple see what properties a style has

    http://www.proinse.de/ogame/cssviewer-1.0.3.xpi

    open it with Firefox and install

    Have fun for Firefox 6.0.*
  • Basta baixar o xpi, extrair com 7zip ou outro e editar o install.rdf, mudando 3.0.* para 5.0.*.
  • For those who LOVE this addon and want to activate it in FF4:
    - Download the XPI (right click in the button "Add to FF" -yes, even if the button is deactivated in FF4- and save)
    - Open the XPI file with 7Zip (you can use other decompressor if you want).
    - In the compressed archive, edit the "install.rdf" file. (A text editor as notepad is enough).
    Find the line (L.18) with this sentence: "3.0.*" and change "3.0.+" to "4.0.+".
    - Update the compressed file.
    - Install the edited XPI file stored in your pc, restart FF4 and that's all!
    - After the restart (FF), click on the buttons bar and "Customize" it. Find CSSViewer at the end of the list.

    I have been using this addon with this manual modification with no problems. Maybe you can find a bug, but I don't think so.
    Kind regards from Argentina.

  • This is an indispensable add on for web developers.
  • There are tremendous problems with CSS incompatibilities, this is a great tool that we're using to overcome them.
