I was thinking of updating to Firefox 4 (currently running Firefox 3.6.15 -- hold on not a software question specifically!) and had some concerns when it comes to web development.
My only concern is if there are any compatibility issues (CSS / HTML) or quirks between the two. I would hate to see something like a 3px spacing while using Firefox 4 on one website vs 0px using Firefox 3 (almost like an IE6 vs IE7 vs IE8 fiasco, if you get my drift).
Ultimately I am just checking if Firefox 4 is business as usual with the display of a website / web app with an updated 'engine' (which is what I expect).
Thoughts? Has anyone compare at this level? And I'm not just talking things like on the CSS Reset level, altho I am thinking along those lines of compatibility.
Hopefully I am making my concern somewhat clear. I couldn't seem to find any comparisons other than enhancement list to FF4 (over FF3), I don't mean to make this a software question but rather, should I be aware of any output changes that I am missing by upgrading. I don't want to miss critical differences when it comes to development and browser compatibility for the customer.
Thanks.

Developer Edition is 12 weeks ahead of the regular version of Firefox with adding support for the latest additions to web standards. You can use the lead time to test out new features, and update sites to take advantage of them in advance.
Firefox has different versions of the same browser. Let's see what the five alternates offer and how you can use them. Do you think there's only one version of Firefox? In fact, there are many alternative versions of the browser, providing experimental features or development tools.
Firefox is the short name for Mozilla Firefox and is a web browser. Mozilla is the company that makes the Firefox web browser. The word Mozilla was also used to refer to the Mozilla suite until Mozilla discontinued development (at version 1.7. 13 back in 2005) and the SeaMonkey community took over the suite since.
Firefox Developer Tools is a set of web developer tools built into Firefox. You can use them to examine, edit, and debug HTML, CSS, and JavaScript.
