Hi.
Running as I do on an ibook, I've got quite a lot of experience with
this problem, and I hate to say it, but whether you can leave these
settings off kind of depends.
I'd say java can always be turned off. Javascript, on the other hand,
gets used in a lot of sites, and for a lot more than just graphics and
animations. You can get really strange stuff like whole sites not
appearing because the text gets generated by Javascript, links not
working because they're javascript links and so on.
My suggestion is, leave it turned off for a while, but if strange
things start happening, reenable it and redraw the page and see if it
helps. If you're anything like me, you'll be turning it on and off
depending on what you're doing at the time.
I keep meaning to try and work out if I can write a script to toggle
it with a keystroke, but I haven't gotten around to it yet.
Oh, and something else with javascript, and the reason I've had to
leave it *on* by default, and not off, is that other applications use
it. For example, I use the task tracking application IGTD. One of its
features is that if you're on a web page, you can hit a hotkey and
it'll enter a task into the app with that web page title as the name
and the URL in the links field of the task. the problem? The author's
used javascript to get that information into his program. So if I've
got it turned off, I hit the key and absolutely nothing happens.
Again, maybe some day I'll rewrite his script not to use it, but it's
an example of really strange things that can happen without javascript.
