I have the default version of firefox (version 19.0) that came with my openSUSE 12.3 installation but I'm looking to update it to the latest version. I've checked YaST and the openSUSE and Mozilla documentation but I've failed to get the new version.

Also, I've looked to install Opera but YaST didn't help and neither did their website.

Any help on how to install firefox and Opera would be appreciated, thank you.
