My point, is
I dont think none in world is looking for a me to rapped me, isnt it?, I dont think none knows me, they dont know my ip, they dont know what its within my computer, and i dont think we both concur in same temporarily gap activity, language, or whatever... and given into my ip, and getting to listen and trying to operate me, when i can inmediatly close the browser or turn off the computer. I mean, to be rapped for someone, there must be a good reason for it. isn't it?? None with enought hacking knowledge was going to put such an efforts at sniffing trying to hacking me in anyway without knowing what is behind the router, there must be a known and good reason for it,i think you can get my point.. Perhaps if i were a knowed server bank, i could be worried to not being enought secured.
I see it really silly the critycal worry of having to update the browser in a linux system. It can't be infected in the code as we're talking about linux persmissions , to practical effects, the app is behaving as it was a hardware device or an old Livecd. And we dont put to update router's firmware everyday, dont we?. Its secure by itself in the same way as any linux apps, as long as they can't hack the user, they cant operate. I dont see it..Its similar to being infected by a virus. I think we've more chances to see The Loch Ness Monster that being hacked.. its just my feeling.. but somene said so about linux viruses, they exists, but none has never seen them, and none knows someone that has ever seen them.. i read that recently in a linux article

.
The only risk i see here with outdated browsers, might be with an infected addon ..supposing that's even possible (by exploiting a vulenerability browser's hole in remote and behing router).
