When you say it didn't work, does that mean that the item I asked you to delete wasn't there, or that you deleted it and relaunched Safari, and nothing had changed?
In either case, please select Help > Installed Plug-ins from the Safari menu bar. Besides the following, what plugins are listed?
Java Applet Plug-in
WebKit built-in PDF
It deleted, I emptied my trash, and restarted Safari. Then, I clicked to get a PDF and the screen was black.
Safari Montage Connect Plug in 4.1.1
Safari Montage Player
Shockwave for Director
Silverlight Plug In
I hope this helps!
Thanks for your time-
The Adobe PDF plugin is still installed, or another one is. From the Finder menu bar, select Go > Go to Folder... and enter the following in the text box that opens:
Press return. Delete anything in the folder that opens that has "PDF" in the name. Then repeat and enter this:
Again, delete anything with "PDF" in the name. Quit and relaunch Safari.
