Firefox beefs

Maybe someone can help me out. I've got some issues with Firefox that I can't seem to work around.

1) I cannot click any links until a page is finished loading. This is especially bothersome on stock photo sites. It's not as big of a deal at home, but at work where I have a slower internet connection, it drives me batty. Is there an option to change this "feature".

2) Firefox loads certain areas of a page before the images when loading. Is this a feature for 56-k-ers? Can I turn this off. I would rather wait for the entire page to load than to see the page as it was not meant to be displayed.

3) This one seems random, and I can't put my finger on it, but sometimes when I only half-way click on a link, or click on it and drag my mouse off, the link doesn't open. This may be related to issue #1, just wondering if it is or isn't.

1) i doubt it. i don't think it's a feature, just the way the page renders

2) no, just the way that engine renders pages.

3) it launches links on "mouseup" so it's not supposed to click the link if you click and then drag off of it.
