If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.
Thank you for the help with the PDF issue Linc Davis! At least the PDF's are now downloading and opening with Reader, instead of just going to a dark grey Safari screen. So thank you for that! Can't believe I didn't look in there myself and try that!
Anyhow, still wondering WHY would they take out the RSS feed reading funtion out of Safari!? It really helped with web development and making sure that the feed(s) you were working on were working, the right ones, and much more... A very backwards move if you ask me!
At any rate, thanks for the help with the PDF issue!
