I'm having a pdf problem also. I'm trying to view a pdf file in Opera 30 (Windows 7). It just won't load on some pages. In Firefox and Internet Explorer everything is fine. So I disabled all of the pdf plugins for Opera. Still no difference. For some reason, Opera tries to open the pdf file in a tab. (I like it in a tab, if it would do it okay, or outside Opera, as long as I can ready the file). Crazy. I went to Opera://plugins, and I disabled the Chrome pdf viewer, the Adobe Viewer pdf viewer for Firefox or Netscape (not sure why Firefox or Netscape on it?), and Silverlight (as I believe someone has posted that's a pdf viewing plugin for microsoft. I don't think I have any other pdf viewers. Still, the pdf file opens in the tabs, and won't open some pages fully. Any thoughts on how to fix this so I can view pdfs okay using Opera 30.
