Make sure you have the update repositories added (you may need to add 11.1 repositories).
Update to latest firefox by adding mozilla repository
zypper addrepo --refresh http://download.opensuse.org/repositories/mozilla/openSUSE_11.1/ mozilla
remove existing firefox
zypper remove firefox
Install new one (update won't work which is why we remove first)
zypper install mozilla:MozillaFirefox
This will not only give you firefox 3.6 but also update to a version of xulrunner which will work with CQ 7.1.1
Add the following to /opt/ibm/RationalSDLC/clearquest/rcp/configuration/config.ini
Or what ever the xulrunner is for 1.9.2. 1.9.0 and old 1.9.1 won't work!
Add the same line to /opt/ibm/RationalSDLC/clearcase/RemoteClient/configuration/config.ini
to get clearcase remote client to work also!
