Can you see a list of all open tabs in Safari?
Here is an AppleScript that will get the name of all Tabs in all Safari windows and show them in an unsaved TextEdit document.

You can save this as a plain script and access it from the Script menu on the Menu bar if you enable it in Script Editor's Preferences.  Or as an App and it can be placed on the Dock.

tell application "Safari"
    set windowCount to number of windows
    set docText to ""
    repeat with x from 1 to windowCount
        set tabcount to number of tabs in window x
        repeat with y from 1 to tabcount
            set tabName to name of tab y of window x
            set docText to docText &amp; tabName &amp; linefeed as string
        end repeat
    end repeat
end tell
tell application "TextEdit"
    activate
    make new document
    set the text of the front document to docText
end tell
