  • Hello,
    I have two more questions about Opera

    1. How can I add Adobe Reader plugin to Opera? I heard it crashes but I just want to know how can I add plugins since I haven't found any plugin folder or file association...
    2. I use both new and old Opera and I just found out they are both installed in the same Opera folder under Program Files. Do I have to be afraid of corrupting the new Opera when I uninstall the old one?


  • 1: You do not add plugins directly, they are installed by the software that includes them. For PDF, you can use Foxit Reader or the PDF.JS (PDF Viewer) extension from Opera store,

    2: The new Opera keeps user data in user profile (AppData), so theoretically, it's safe to re-install it. I'd backup both folders, %programfiles%\Opera and %appdata%\Opera Software\Opera Stable, uninstall Opera, delete %programfiles\Opera, and install the new Opera. I don't do it though, because I need O12 for testing and uninstalling it would only give me 45 MB of space, which is insignificant.

  • How can I add Adobe Reader plugin to Opera?
    If you have it installed in your system it should work in Opera. Make sure you have the latest version from Adobe.

    Go to the opera:plugins page so you can check whether it's enabled. If multiple PDF plug-ins are enabled they may conflict so pick one and disable the others.

  • thanks! I totally forgot about opera:plugins!
