I'm still experiencing this in Firefox v8 latest. This problem has been around for a while (since v6 at least IIRC). 

Apparently, there are plenty of bugs on the topic:
Bug 653706
Bug 650384
Bug 639332
Bug 368602

A few extra info:

- The problem occurs 90% of the time at startup, even before "touching" Firefox.

- Following a useful tip (http://www.tweakguides.com/Firefox_10.html) I've changed the default setting of one environment variable (namely browser.sessionstore.max_concurrent_tabs) in order to get the same behavior as the defunct BarTab plugin (https://addons.mozilla.org/fr/firefox/addon/bartab/). This in order to avoid loading more than one saved tabs at startup. (By the way, why isn't this the default behavior?)
