Hi, you will do better in forgetting you ever had mozilla 0.7 on your box :)
I'll help you how:
* rpm -qa |grep -i ^mozilla
will produce a list of the rpms you installed which have mozilla in the
beggining of the name.
* rpm --nodeps -e `rpm -qa | grep -i ^mozilla`
will erase those such rpms.
To install the new rpm packages, you will need to do:
* rpm -ivh mozilla*6.rpm (to install all the 5 or 6 rpms)
That should work swell enough.
If something goes wrong, I'd figure you've got your system pretty well
damned already, and I will not touch it with a 100 foot pole.
Hugs, rms
