32 vs. 64 bit confusion

hi all,

here come the stupid questions, sorry i can't find a clear answer online

i am building my xcode NPAPI plugin and stand-alone executable in the standard 32/64-bit universal architecture

1) does that mean i can ship my app and it will run on any 32 or 64 bit mac? or do i need to ship two versions?

2) Safari can run in 32 bit or 64 bit mode, you can set that in get Info, will my plugin automagically work either way?

3) I am having trouble getting xcode to launch (say) Safari as either 32 or 64 bit to test both issues, can this be done?

4) FireFox can't run 64 bit yet, so will it automatically run my 32 bit version on a 64 bit machine?

5) I have some dynamic libraries i use, is their usage as 32 bit vs 64 bit automatic based on opening them? I don't do anything special...



thanks in advance,

bill appleton
