Does this use the same process-per-tab sandboxing that Chrome uses? I'm one of those crazy users with far too many tabs, and I was always sceptical that Chrome would be able to handle them all. Opera always ran happily with 100+ tabs.
Perhaps this is the reason for the introduction of the 'stash', which in fairness might be a better solution (as I'm not necessarily defending 100+ tabs, but its a habit that has worked for me so far)
That site seems to be created specifically for bloated browsers like Chrome. 1981 MB memory used for around 20 tabs? That's crazy. And why would you pack so many tabs on just one single line?
In Opera you can (at least for now) wrap your tab bar on multiple lines, show an extender menu, disable it (and scroll with right mb + wheel) or simply move the tab bar on the left/right side of the screen, while having a decent resource consumption, all out of the box.
Edit: now I realized it is indeed created specifically for Chrome, it's an extension that tries to help circumvent poor browser design.
