I know both browsers are good and I'm beginning to ask if you've got shares or something, BUT do you whole heartedly believe that if all the attention turned from Microsoft's Internet Explosion to these browsers that they would hold out... after a short period of trial and error from "security experts" I don't think so
It's only because no one has gone after these browsers, YET!
They will have holes, flaws and breeches... we just don't know where yet.
Me I'll just turn off ActiveX, run Norton update every day in the background and hide behind both my routers firewall and the one on my pc, and surf with the browser that works even if the page is coded kinda sloppy knowing that today might be the day.
