...Thank you again for the tip on using G3 version unsupported in early Intel-based Mac.
I've a first-edition MacBook1.1 13-inch 1.83GHz coreduo model w/ Leopard 10.5.8 and
this works very fast, goes almost everywhere well. ~ Much better than G4 1.5 GHz Mini
Mac (Late 2005 last build) which also runs Leopard 10.5.8 very slow due in to PPC build.

I've not tried any FoxBox versions in theTenFourFoxG3 running on intel-based Mac.
Never did resolve issues 'using original samples' of FoxBox in PPC G4 Mini Mac.
But this G3 version unsupported with three items in 'about:config' set to False does great.

Because I have four or five Macs here and two iOS devices of varying vintage, the newer
Mac mini i7 has it's fix w/ modern browsers & runs well online. Seldom use it's quad core
processors outside of reference point, and it dual-boots 10.9.5/10.11.6.

The iBook G4 (mid 2005) reverted to Tiger 10.4.11 does OK with TenFourFox G4e version,
in an otherwise original configuration as bought in 2005 from Apple; except 1.5GB RAM.

Thank you again Cameron for this otherwise impossible option with first edition MB1.1.
Best regards..! :)
