For whatever reason, I can't use (mac) mail on G5 with Charter. Would like to try Thunderbird (TB) -now using Firefox 3.6.28. But can't navigate through Mozilla to find older versions of TB. Other alternatives

I have recently moved from Thunderbird to SeaMonkey - much better and up to date with the latest Mozilla code.

See my SeaMonkey page at: http://links.zero.eu.org/seamonkey/

For PPC - download the latest SeaMonkey-ppc from:

https://code.google.com/p/seamonkey-ppc/downloads/list

For Intel - download normal SeaMonkey from:

http://www.seamonkey-project.org/releases/

Old versions of Thunderbird can be found here:

ftp://archive.mozilla.org/pub/mozilla.org/thunderbird/releases/

The latest Thunderbird for PPC is 3.1.20.

The current release of Thunderbird says it will run on OS X 10.5 or later, and recommended is a mac with Intel processor and 512MB of memory. Older versions of TB can be found here.
