Even the fastest TiBook cannot cope with the expectations in any web-browsing.
Nor with Classilla neither with TFF.
To choose a TiBook over the fastest PowerBook-G4 (the DLSD) has not been wise.
Thinking too much about that too much is also not an option!
(full stop)
Any 15" Core2Duo MBP from late-2008 or later (c2duo!) or a/THE mid-2012 15" MBP would be the machines, that might cause lesser pain, than those ones, you've already tried.
No intel i5/i7 15" MBP from 2010-2011! No early-intels (up to early-2008)! All of them are prone to GPU-failure!!!
Forget about the combination of Your TiBook and Web-Browsing. That's only a source for getting depressions.
The Ti-Book is fine for os9 (and more), but severely limited, when it comes to compressed-video and web-browsing.
PowerPC is either a specialized tool, a piece of collected computing-history or a toy, but no such think to make you happy with internet-browsing, cloud, commercial-video-streaming etc.
Please take that advise...
Hi, I may try Dronecatchers grease monkey script and view something to try and watch some youtube. I also will be getting another PB G4 1.67 soon, but for some reason I just wanted a TI G4. So far, nothing is artifacting. However, I guess I can live with the one speaker not working. I have also a 2011 MB Pro with a bad battery - not ideal for web browsing or anything else. I also have a 2012 Macbook Pro - bad memory chips though are preventing the thing from letting me install Catalina.. Strangely, it works great on Mavericks.
