Upgrading to Firefox 3.0

I've recently run an update of my web browser to Firefox 3.0 and I must say, superficially I can't see too many differences. Some of the interface elements have increased in size. Although I suspect many of the improvements are under the hood in terms of rendering and new standards support.

One thing I did notice though is that during the upgrade, all of my previously installed add-ons like Firebug disappeared. I didn't expect this and I'm pretty sure that there was no advice on this in the upgrade process. Still, it wasn't too painful to find and install them again ...

However I have experienced numerous severe crashes, particularly on some sites and incompatibility issues with some rich text editors which has seen me go back to Internet Explorer. Currently Firefox appears unstable, and I'm not sure why they released and promoted such a buggy browser ...
