When I lose firefox (usually when power outage) I just cycle through all the tabs with ctrl+tab, by the time I get back to the first one it has reloaded (and the others do so in the background). It's not a big deal.
Thanks for the advice - hopefully it helps others. For me, it happens infrequently enough that I am unlikely to remember anything specific for the situation. I never select multiple tabs otherwise.
