Why are my new, blank tabs titled "Untitled 2"?

does it persist in other or new/guest user accounts ?

any Safari extensions enabled ?

If so, test without.

Failing that, triple-click to select the line below & choose Services-Reveal from the Safari or ctrl-click menu.

~/Library/Preferences/com.apple.Safari.plist

Then with Safari Quit - move that file out to the Desktop. Test Safari again after setting 'tabs open with'...

any better ? - If not, quit safari & replace the file, overwriting the newer one.

This file contains most all safari settings, including those for extensions... so restting all those may not seem worth it for this.

I found that I can get that, but only if more than two safari windows are open... yet you see this with just one. This is on 10.5.4 as your profile, or...?

I thought I'd chime in on this thread even though it's old, because it's the first hit on Google about this problem.

I fixed this on my copy of Safari by doing the following.

1. Close all open Safari windows (not tabs). You should end up with just the menu bar and no open windows. (Keep in mind that you'll lose any unpinned tabs by doing this, so bookmark/pin/etc. any tabs you want to hang onto.)
2. Go to the Safari menu and select File/New Window. Any new tabs will now only say "Untitled" and not "Untitled [number]".

After researching this problem, it seems to happen when a new window (not tab) is opened, and the original window is closed, so even though Safari only shows one open window, it still considers that window to be the second one opened, and therefore labels all tabs in it accordingly ("Untitled 2").

While the "Untitled [number]" issue is a bit of an annoyance for those of us with AR tendencies, I would think it would be a simple fix for the Safari team, so it's possible it will be addressed in a future release. In the meantime, this workaround seems to work for me, and hopefully for anyone else. If not, please post.

Thank you very much
