"Who wants the keys?" Rated 5 out of 5 stars
quoting from http://philikon.wordpress.com/2011/12/02/the-future-of-bartab/
"Since Firefox 8, you can tell Firefox to only load your tabs on demand, just like with BarTab. You can find this setting in the Firefox options/preferences dialog:"
"As far as BarTab’s future is concerned, there might be hope. People have forked it on GitHub and apparently made it work (great work, whoever you are!), other people have made XPIs with fixes available. This is awesome, but I can’t just merge their work and release it. At least I don’t want to put my name on something that I haven’t thoroughly reviewed and tested. But, if somebody else wants to take than on, I’d be more than happy to hand the keys to BarTab over. Please get in touch with me if you’re interested!"
