Proxy setup in YaST - Do I still need to configure proxy settings for browsers?

Hello all,
If I configure my OpenSuSE 11.2 system to use a proxy server in the YaST Proxy module, do I still need to configure my browser (i.e Firefox) to use these proxy settings, or is it done automatically under the covers?
Thanks in advance.

Hi… I’m interested in this as well…
any help to set it up will be highly apreciated
