Trying again to ask a PROGRAMMING question because of the over-zealous closing off of what is equally a programming question before allowing the poster to clarify.

The latest version of Firefox (v3.6.3) is breaking websites, mine included. I make heavy use of the Infragistic NetAdvantage controls. These, because of their heavy JavaScript reliance and occasional lack of quality control, tend to suffer through browser updates sometimes requiring a hotfix.

So the question is... has there been a Firefox release recently that has either introduced a bug, tightening up of some standard, bug fix which might have broken a previous workaround (often the case) etc?

I'm guessing around JavaScript but that's a guess hence the reason for asking a group of programmers...

Have you tried looking at the latest release notes? – Jamie Keeling Apr 11 '10 at 17:46

This is still not a programming question - just because it affects something that has been programmed doesn't make it one. By that logic, any computing question is a programming question. Try again on Superuser, or perhaps check Firefox's Bugzilla? – Adam Wright Apr 11 '10 at 17:47
I've checked the ig charts in my project and no issue was found. ff(v3.6.3). I'm not sure about the other controls. – Hanseh Apr 11 '10 at 18:10

@Adam: it is a questiona bout what has changed under the hood in Firefox (from a programmer POV) which makes it primary StackOverflow and not ServerFault or even SuperUser. Esp. as further investigation suggests a coding change is going to be needed in the JavaScript. – Rob Nicholson Apr 11 '10 at 20:49

Almost all Firefox may break web sites, but they usually don't intend to. I follow Firefox development closely and there wasn't information about changes that needed fixing on the web developers' part; there certainly are bugs but nothing really outstanding.

There's nothing you can do without more details about what is broken or when it broke (i.e. an exact regression range). With enough details and bugzilla-fu you could try to find the ticket about the issue to make sure it's tracked.

If you have a testcase, please file a bug in bugzilla.mozilla.org and make sure someone looks at it (e.g. by asking around on irc.mozilla.org).

Later... there has been a change in Firefox starting with v3.6 which breaks several sites inc. Google Maps. Initial investigation suggests a change has broken event handling in JavaScript. This is either a legitimate change has been made which requires a change to the JavaScript code on effected sites or a bug introduced into FireFox requiring a new release of FF. The current workaround is to downgrade back to v3.5.9 until a resolution is found: oldapps.com/firefox.php?old_firefox=78?download – munrobasher Apr 11 '10 at 21:42
