It seems that the Toyota site does not render correctly with Firefox under Linux (with Flash plugin enabled). It definitely has something to do with the Linux version of Flash and how the site was constructed. Continue reading ‘Flash Site Compatibility Issue’ »
Flash 10 just came out a few days ago, and I just installed it using the information provided on Ubuntu Forum (I used the script from here to install on my 64bit Ubuntu). Continue reading ‘Flash 10 on Ubuntu 64 bit — Significant Performance Improvement’ »
