At this stage, after months of development, Mozilla developers are clearly nearing the end of this development marathon.' After Firefox beta 9, a beta 10 and a single RC are scheduled (this road map can change, of course). The main features of Firefox beta 9 are IndexedDB and tabs on titlebar (just like Chrome and Opera). IndexedDB allows sites to store data on your computer (with your prior authorization). Tabs on titlebar is self-explanatory. Old-schoolers can always turn on the 'show menu bar' to get their familiar GUI back. Oh, and Fx beta 9 is fast and starts fast. Firefox beta 9 available here and in lots of official mirrors."
