Deferred loading in tabs in Firefox

Submitted this request for Deferred Tab loading to the FireFox bugzilla.

The problem essentially is that when you do "Open in Tabs" from a bookmark folder or have multiple pages ('|' delimited) in your home page; the urls are loaded simultaneously. Woudn't it be better if the first site loaded and then after some time (say a second) the second site loads in the second tab. So while you read the first site, the next couple of sites load. This would especially be helpful if you load a lot of sites, like I do, using the "Open in Tabs" option.
