How to name Tab Groups in Safari ?? - it does not work as described in Apple Help pages
I want to file related bookmarks into different relevant Bookmark folders and can easily do this on a Windows PC using say Mozilla Firefox browser, but here on the Mac Safari browser the process is clear as mud to me. I have followed the scant instructions but what is present under the Bookmark sidebar does not correlate with the help page instructions: They say...
Create a Tab Group from the tabs in the current window
- In the Safari app
on your Mac, click the down arrow 
next to the Sidebar button 
in the toolbar. - If the sidebar is open, click the Add Tab Group button
in the toolbar. - Choose New Tab Group with [number] Tabs.
- Enter a name for the Tab Group, then press Return.
....Steps 1 and 2 above work just fine but steps 2 and 3 are not possible because as soon as I create a new empty tab group, it creates a new desktop Safari page and I lose everything I have been working on, and in any case, clicking on the new 'Untitled 1' tab listed under Bookmarks does nothing on a left-or right click - there is no opportunity to number or name a Tab, plus I lose all my previous work. It is a disaster.
Is it best to avoid this function as it seems faulty?
