I’ve been busy doing analysis for the next article in my cio.com Firefox series of articles, looking at vulnerability disclosures during 2007 and 2008 and I stumbled upon a little factoid that I had not previously noticed – no single version of Firefox was available for the full year of 2008.

In retrospect, I should have known this would happen, given the Mozilla policy of supporting the predecessor version for 6 months after a new release.

Here is what the timeline looks like:firefox-version-timeline 

In my interactions with customer councils, I’ve found that enterprise administrators expect longer support lifecycles and much longer transition times than those shown here. 

On the other hand, maybe it is different for IT departments managing browsers in the enterprise than it is for other applications …

I’m curious, what are your thoughts on this?
