Browser security -> 'new' releases

Hi List, Just would like to ask, maybe somebody knows about SUSE's strategy, how it is planed to release new (~fixed) versions of browsers as Opera, Mozilla, FireFox... I know, that a YOU-update for the above browsers after a single security fix would be useless; but is there a (per-) scheduled time when bug and security-fixed versions appear e.g. via YOU, or there should be a huge security-flaw to trigger this?! For Mozilla I found the 'ftp://ftp.suse.com/pub/projects/mozilla/' folder, which includes FireFox as well, I wonder if something like that for Opera could exist... Thanks a lot, Peli
