I use SpeedDial as my homepage and up to the latest revision it worked fine. Now my homepage (chrome://speeddial/content/speeddial.xul) no longer comes up in a new tab. I see from reading that this is no longer possible to make work. Hopefully there will be a work around soon. I've always used Firefox mainly due to the great add-ons available but it seems Mozilla is making it very hard on the developers. Nearly all of my add-on's show "legacy" with I suppose means they'll stop working in November.
