Update: I was using Timberwolf with an older archive. I also noticed that making a couple changes improved performance. I got the ~newer~ version of Timberwolf and added the files from the LZX archive (read above). From Tools/Options changing "When Timberwolf starts:" to "Show my windows and tabs from last time" helps a lot. This also makes "about:config"'s "browser.showQuitWarning" not needed, so keeping it at false. If this is made to true then Timberwolf causes or crashes when you exit it after you're prompted to Save tabs. I've now been able to run it from whatever partition and filesystem.
However, it does have a memory leak (2MB...??). If you exit and start it often you'll notice it. It also becomes slower and causes X5000 to hang a bit if you use more than 5 to 7+ tabs, as I do with Firefox...I have more than 10 usually. Same with WinUAE 3.6.0, of course.
So, it's a cool browser with this understanding but it's not as powerful as Odyssey...but has great potential if it were to be developed. It loads a little faster than Odyssey (not a problem to me, just observation). But a big point...it won't play YouTube videos or videos from other sites like Odyssey does. Anyone getting into or wanting to use Timberwolf, it's still a very good general browser. I'm glad to know that it does indeed function on SFS02 as I previously thought it does not; and only on FFS.
A side note, from "about:config" ...if you filter with "Firefox" and change "general.useragent.compatMode.firefox" to true then you won't get warnings about the browser being outdated as much, or sites informing you your browser isn't supported. :-) I'm sure there are other tips I haven't discovered..and maybe there's a Flash/Shockwave plugin or Library I haven't discovered yet..anyway, cool Browser. I hope this is helpful to others.
