1.You need a website with very slow response (Like b.m.o sometimes get these days) where it will take a loooooong time to load, and sometimes even throw a 502 errror
2. try to open a tab like this
3. Put that tab in the background
4. Wait
5. After some time, the loading throbber of the tab becomes a "hourgalss" - See attached screenshot.
6. Now close firefox and reopen. Use History->Restore previous session
7. The "hourglass" tab from Step 5 will have a blank tab-title

AR:

1. The throbber becomes a static "hourglass" icon
2. On session restore, the tabs with the hourglass icon have an empty/blank tab-title.

From bug 1812019, i am guessing that the hourglass is the intended behaviour?
But is the blank tab-title on session restore also by design?
Edit: The two issues I described may actually be separate issues, i just filed the bug as I understood it.

There may be a bug on file for this already, but I wasn't able to find it. Essentially we should considering recording the URL of the tab in the session, even if we've not yet got a response from it before the browser quits and the session gets written. I've seen this cause data-loss if you restore a session in the browser without a stable network connection (say on a train), then when you restart again at home you find all those tabs got replaced with about:blank.
