web browsers
Tenfourfox mostly, though latest 9 builds seem to have taken a bit of a performance hit with Kaiser and Co trying to get method jit and/or tracejit running stable. Tenfourfox 8 is fast,fast,fast. Omniweb and sometimes Safari, and sometimes G4 optimized builds of Camino.Been using greasekit and viewtube in Safari and Omniweb to play youtube inside a browser the last few days, which is a revelation. However mactubes is still the way to go to get your youtube on PPC machines.
And of course Classilla. Posting from 9.2.3 right now. Classilla is frackin great, especially if you make extensive use of mobile sites. Most of the content, none of the ads! I hope Herr Kaiser can keep it going.
