First difference is the choice of fonts and most notable difference is the "CSS" fonts rendering, while RPM based mozilla renderes the page correctly the tarball based mozilla fails to do so. Reproducible: Always Steps to Reproduce: 1. Install mozill-1.3 RPM on Redhat 9 2. Install Mozilla-1.3 tarball on Redhat 9 3. Run RPM based Mozilla and access http://news.google.com and notice the page. 4. Close the RPM based Mozilla and start tarball based Mozilla 5. Access page http://news.google.com and notice the page. Actual Results: You should be able to notice the clear difference in the font rendering.
The RPM builds use GTK2 and xft. The tarball does not. Which means that the two builds see totally different available fonts -- the tarball sees whatever the X server sees, whereas the RPM sees whatever xft sees.
