Kaspersky is still behind on supporting Firefox 9 as per http://forum.kaspersky.com/index.php?showtopic=224799

I am still running vers. 7.01, which also disabled part of my Kaspersky security features. I have refused to update since then. A browser that will not accept the security features that I want to protect my system is not useful to me. I will soon be dismantling vers. 7.01, to go back to an old version also. I just had not gotten around to it.

First, let me say that I totally appreciate all of the hard work that has been done to make Firefox a top browser. With that said, and the demonstrated experience and capabilities of the software developers, why isn't there more collaboration to ensure that items widely in use by users (i.e., Kaspersky, Adobe Acrobat X/Reader, etc.) is still functional when a new version comes out? For the commercial companies, it would seem that it would be in their best interests to insure that their product was functional.

Some have gotten better in their support of Firefox releases. For example Norton has a update patch pretty much on day of Firefox releases (or very shortly after) now (ever since Firefox 5.0) and not the be typical 5-6 weeks after a Firefox release of before.

They can easily use the Beta builds of Firefox to test their products extensions as chances are when the final release comes out they have to do very little if anything to be ready for scheduled Firefox release.
