Kaspersky is always late for updating their Firefox add-ons, Mike. The first time I installed KIS 2011 after winning my key from you, I found their three Firefox add-ons were not compatible with Firefox 5 (or was it 4 (?)) either. And when they were ready, guess what? Firefox 6 (or was it 5 (?)) was released a week after that! And there goes the setback happened again.

But Kaspersky is not the only one. With this rapid release cycle that Mozilla takes, we may find other companies that miss the train too. Techsmith, for instance. They have not updated their Snagit add-on for Firefox 3! Only download manager applications, such as Internet Download Manager or GetGo, which seems to be really putting effort into catching up Firefox release schedule.
