Yesterday Mozilla released Firefox 5.0 as part of its rapid development cycle. This has implications for Firefox 4.x users.

What implications? Well, basically the upshot is that Firefox 5.0 is a security update for Firefox 4.x users (Firefox 4.0 and it's only update, Firefox 4.0.1 which was released in April). This means that is Fireflx 4.x users want access to security fixes, they need to upgrade to 5.0.

This has been confirmed by Asa Dotzler, community coordinator for Firefox marketing projects, on Mozilla's mailing list:

That being said, there already has been a 4.0.x release and there may be another if a critical security issue arises that requires a "chemspill" unplanned emergency fix. But that would be an *unplanned* emergency release and not a planned one. The planned security update for Firefox 4 is Firefox 5.

So, unless Mozilla release an unplanned emergency fix for the Firefox 4.x line (I like the name "chemspill"), users will need to go up to 5.0 for the security patches.

Worried about extension compatibility? According to Mozilla some 80% of extensions are compatible with this release, but that still leaves a good number of extensions that are currently incompatible. If you rely on certain extensions, then you could be caught between the rock of workflow disruption versus the hard place of exploitable security issues.

    That's all fine and dandy, but how is Mozilla going about convincing 3.x users to upgrade? I still see a TON of users still using 3.x (My college campus included).

      Mozilla released 3.6.18 on Juni 21st. That'll probably be the last update for 3.6, I think.

    FF5 has been working great so far for me. All the add-ons work with the exception of the garmin add-on. It says its not compatible but I ignored it. Haven't tested it out yet though.

    Sheesh, I just got 4 a few months ago, now I have to install a whole new version and test it with the sites? What gives? If they are going to do a complete new release every few months, I'm ditching FF. Not that they care, mind you.

      @bigsibling - It's mostly just the numbering system that's changed, not much in the way of new features in this update. As far as actually speeding up development, the only change with the new system is that releases won't be held up for new features that aren't ready - when a new release is due, it will be released with those features that are ready to go.

      @bigsibling - I use Linux, so until now I had to completely install a new version of FF, but I went from 4.01 to 5.0 automatically, so it SHOULD do it by itself. AFAIK...

  • Big security issues.

    This is bad because this release does not use an automatic update mechanism.
    Many people will stay vunerable to security issues solved in the FF 5.0 release which are now public knowledge.
    Sysadmins will hate this big time as this is forcing them from patching to doing major update releases every few months.

      Automatic Updates is still listed in the Options > Advanced > Update section.

  • FF5 is not part of 'rapid' development; it is part of usual development, ..

    .. with just numbers inflated -- as well as in Google's Chrome.

  • What's the matter Adrian, sour grapes?

    Or, are you hung up on versioning number schemes?

    Here's how it work going forward, regardless of what is in the release.

    Next version: take previous version number, add 1 to it.

    That's it.

    Questions? (wink)

    Agile programming is the ticket!
    Watch out Microsoft.

      This is NOT Agile programming. This is simply short-cycle iterative development, or simply shortening development cycles by reducing the number of features. Agile is about how the development team works together and delivers the CORRECT product of high quality, not simply how quickly they deliver.

        Well said. Also, the lack of auto-update is a pain in the arse.

      There are lots of software development fads. Why are you pushing this one all of the sudden?
