I have just loaded both the Thunderbird 1.5.09 and Firefox 220.127.116.11 versions on a 64bit Mandrake 10.1. (Since I ahve yet to get the 2007 to work under apache and PHP and find the man10.1 is the only version that works.
It is much easier than before to download these two versions now, but not as rpm's.
I went to www.mozilla.org
and clicked on the download of each one and downloaded to where I wanted them to reside. Unzipping creates a directory from where they operate from.
my example for thunderbird was in a terminal in the directory where I had downloaded them to I typed
gunzip -c thunderbird-18.104.22.168.tar.gz | tar xvf -
then changed to the directory where the decompressed files were
then ran it with the command
this took all my previous mail and put it in my new version.
I then edited my desktop ikon to point to the directory
I did the same with Firefox but this insisted I reboot as it kept saying that I had a firefox running even though I couldn't find it.
Firefox 2.0 then booted with all my bookmarks still there again. I then changed the ikon again to point to the new firefox.
One thing I still have been unable to do and I hope someone can help on this is when I click on a URL in thunderbird it will not fetch up the firefox browser.
Anyone knows how to do this I would appreciate the help.
