What's up with MooTools and Script.aculo.us?

[CloudedVision]

I'm making a site that does the following when a user navigates to a different page.

1. Page slides out of view
2. AJAX gets the content of the new page
3. Page slides back in

So I need a javascript effects framework like MooTools or script.aculo.us. I've heard some good stuff about MooTools, so I download that. (The beta) It gets an error in firefox. So I downloaded the latest stable release. That still gets an error. (So much for "stable")

So then I go to scriptaculous. I download it, and do the basic implementation. The simple slide effect causes firefox to freeze all javascripts on my site. And also, when I write a line thats obviously an error, it stops firefox from showing it as an error in the javascript console.

So whats up with these javascript effect frameworks. Why can't I get anything to do such a simple task? Could anyone help me get these tasks done?

If you want a simple solution, go for jQuery.
You can code what you just explained in just a few lines.
jQuery easy to understand. Easy to learn. Easy to use.

I'm short of time now but let me know how you get on...

Mootools has a good and bad points... and there download compiler is aweful.

Alot of things you request in the download compiler and download are dependent on other factors that aren't compiled into your download, always download the full commented version for working with.

I've heard good things of JQuery, never used it though.
