I'm sorry for all of the questions, but I decided to get them out of the way. I've heard that there are some Internet features that OS X Tiger doesn't support that OS X Leopard does.Is that true? I current run TenFourFox on Leopard with a 1.67 Ghz PowerBook G4 and would like to reformat my computer with Tiger instead because I like the support for Classic Mode and ShapeShifter. Are ther any things that TenFourFox supports on Leopard thatit doesn't support on Tiger?

    TenFourFox *could* support more web features if it was 10.5-only, but since the primary goal is to make it compatible with 10.4, it doesn't.

    Problem with 10.4 is that while it gives you Classic, there's no Leopard Webkit available, hence no updates to systemwide security certificates and no up-to-date systemwide Webkit. I.e. no modern Safari browser with WebGL and full graphics acceleration, and you'll run into trouble with Apple Mail, iTunes etc. if they try to connect to more modern TLS servers.

    Just to make this explicit: the issue with the system security framework in 10.4 applies to everything but TenFourFox, which carries its own encryption library and certificate bundle. However, this support is pretty much specific to TenFourFox and can't be used by anything else for technical reasons.

    I use Tiger exclusively, but I have a lot of Classic apps I still use and I prefer the look of it. On a 1.67GHz G4, I wouldn't expect a large performance difference between Tiger and Leopard, so if that's your main motivation I agree with Chris it may not pay off in terms of what you would lose.

    I thank both of you gentlemen. The work all of you do is greatly appreciated. I'm not interested in performance, or else I wouldn't be using a PPC Mac. I also understand a tradeoff Webkit vs. Classic Mode and ShapeShifter--both of which only work under Tiger. Apple Mail has always been trouble under any version of PPC operating systems and that's why I use TenFourBird which works like a charm. And webkit, according to SourceForge, hasn't been updated since 10/8/18. I guess what I'm asking is will there be any differences running TenFourFox FPR 16 under Tiger as opposed to running under Leopard? Again, I thank both of you gentlemen. Ps. Do you think there will be any troubles running TenFourBird (which quit developing in 7/27/16) or SeaMonkey's mail client (which quit developing the Tiger version (2.19) in 2013) as mail clients in Tiger as opposed to Leopard?

    There are some technical differences, but for all practical purposes TenFourFox is the same on 10.4 and 10.5. The same should be true for TenFourBird.

    BTW Apple Maill in 10.5 is the most stable, reliable mail client with the best performance for large mailbox files I've ever used (certainly not what I've seen more recent versions of OS X where it has really gone downhill).
