There is evidence users find this troubling - eg, bug 762610 reports
that a couple of users wrote to the mozilla webmaster about this. While
it may just be a perception, it seems a perception worth managing. And

able to count the columns, or see the balance is written in red.
People can already delete a site using the X button - would making that
more prominent help?
I'm not sure, but I doubt it - they might not still be sitting at the
computer when they notice it (ie, you log out of facebook and move away
from the computer. Another user then sits down and opens a new tab -
it's too late for you to close the thumbnail)
It's not that uncommon for people to "borrow" a machine that happens to
sit in, say, a living-room. If a guest in our house jumps on our
communal "family machine" to (say) log into their bank or quickly check
facebook, I'd expect them to be uncomfortable if their bank screen or
photos from their facebook feed remain as thumbnails after they are
logged out.
This seems to be one of those cases where their discomfort is caused by
actually having some way of noticing something which has always happened
anyway. Their stuff may be still in the cache; and the user could have
installed a logger anyway.
Sure - as I mentioned it's more about *perception* - but that doesn't
make it invalid.
Could we consider using blurring, or just using the favicon, instead of
this seemingly highly complicated parallel request infrastructure?
I'd guess that blurring enough to obscure a red "account balance" figure
or to render a photo from Facebook completely unrecognizable would look
fairly ugly.
I can't recognise Facebook photos from the Thumbnails as it is... The
bank balance is a slightly odd case because it's one where there is
information available from colour alone. And it's only a single bit of
info at that.
I still think we should look at a blurring solution as a much smaller
amount of engineering effort for almost the same win.
Note there are other ways that thumbnails can be missing - blurring
these might reduce that number, but not eliminate them completely. The
missing thumbnails I personally see are overwhelmingly *not* due to
this, so this wouldn't constitute a "win" for me (YMMV, etc)
