I was using firefox 3.6 (or similar). Downloaded new version as directed but it won't let me open it. My operating system is Mac OS 10.5.8. There is a censor sign over the icon.

Current Firefox versions (since Firefox 4) for Mac OS now require an Intel processor and won't work on PPC Macs. See Firefox won't start - find solutions under "Firefox will not start on OS X 10.4 or earlier or with a PowerPC processor".

You can download and install the latest Firefox 3.6 release from http://www.mozilla.com/en-US/firefox/all-older.html
