I would like the browser to throttle the rate of tab openning, something like 1 per 2 second, and maybe waiting until no more than 10 that are currently loading. Because when I try to open 100 tabs it chokes my system for about 5 minutes and sometimes even trigger the remote host's anti-ddos defence so that all the tabs end up broken and I have to reload them a second time.
But that's really the second point.
The first point is "Open tabs from clipboard URLs"
I did find something in the mean time.
It works, but it's a two step process, instead of a single click toolbar button like what I had previously.
