Who mentioned anything about going back to FF2…
You WON’T be going back to FF2… after following your instructions… you now have FF3 at /usr/lib/firefox-2.0.0.14/firefox
Can you (at the moment) still open FF3 ? … either from your desktop icon, or by:
/usr/lib/firefox-2.0.0.14/firefox
I’m going to find it hard to help if you don’t answer my questions, or don’t trust that what I’m saying will NOT harm your system.
I FULLY understand what the instructions you followed did, but if I tell you how to get permission to upgrade FF3 to FF5 in its current location… I’ll guarantee you will be left without a working browser at all.
If you want an explanation…
With your instructions, you effectively moved the original copy of your FF2 directory from /usr/lib/firefox-2.0.0.14 to /usr/lib/firefox-2.0.0.14bkup … then created an empty directory at the old location (/usr/lib/firefox-2.0.0.14) and extracted the FF3 archive into it… so now when you start firefox, it follows the original path and starts the version of firefox that is contained there, which now happens to be FF3 even though it is in a directory called firefox-2.0.0.14
Backing up FF2 in this way was NOT what stopped your desktop from screwing up… the ONLY way that would happen is if you REMOVED FF2 altogether through yum… which ALSO uninstalls a load of dependencies which happens to include half your desktop.
If I tell you how to upgrade FF3 in its current location… you will NOT have the necessary extra file (libstdc++6.so) needed to run FF5, and you will be left without a working browser.
Installing FF5 to /opt/firefox and placing a symlink earlier in the PATH is a MUCH safer way of upgrading to FF5, which will also allow you to start FF2 (or in your case FF3) from the command line if anything goes wrong… and worse case scenario, you’d only have to delete or rename the symlink to immediately go back to being able to start FF2 (FF3 in your case) from your desktop icon.
Now your either going to accept what I’m telling you, or not… but you can see from the comments in the FF5 and FF4 threads that these instructions (barring the AA1 sudo bug or typos) have worked for everyone who has tried them.
I’m quite willing to help you, but you’ll have to decide whether you’re going to listen to me or not, and not try to pre-empt what you think I’m saying
