I-Firefox Isithangami Sokwesekwa

Guys, my browser is going crazy and every website that I am on changes in about 10 seconds to 2 minutes to another webpage. I even downloaded a newer 5.0 version of firefox and I am having the same problem.

Facebook (FB) recently restructured their website. After logging on to my FB homepage, some of the graphics are garbled and I am no longer able to post status updates, comment on friend's status updates or pictures, or post pictures using Firefox version 2.0.0.20. I would like to know if there is a newer version of Firefox that will function with a Mac G3 Blue and White desktop running OS 10.3.9 which will be compatible with the new FB? I would upgrade my computer, but have 22+ years of business and tax records that will not function with the newer Mac OS.

Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.
