Mailing-List Mush: End of Life for Firefox on OSX 10.6-8, ICU dropping Windows XP Support

Apparently I’m now Windows XP Firefox Blogging Guy. Ah well, everyone’s gotta have a hobby.

End of Life for Firefox on OSX 10.6-8

The Firefox Future Releases Blog announced the end of support for Mac OSX 10.6-10.8 for Firefox. This might be our first look at how Windows XP’s end of life might be handled. I like the use of language:

All three of these versions are no longer supported by Apple. Mozilla strongly encourages our users to upgrade to a version of OS X currently supported by Apple. Unsupported operating systems receive no security updates, have known exploits, and are dangerous for you to use.

You could apply that just as easily and even more acutely to Windows XP.

But, then, why isn’t Mozilla ending support for XP in a similar announcement? Essentially it is because Windows XP is still too popular amongst Firefox users. The Windows XP Firefox population still outnumbers the Mac OSX (all versions) and Linux populations combined.

My best guess is that we’ll be able to place the remaining Windows XP Firefox users on ESR 52 which should keep the last stragglers supported into 2018. That is, if the numbers don’t suddenly decrease enough that we’re able to drop support completely before then, shuffling the users onto ESR 45 instead.

What’s nice is the positive-sounding emails at the end of the thread announcing the gains in testing infrastructure and the near-term removal of code that supported now-unused build configurations. The cost of supporting these platforms is non-0, and gains can be realized immediately after dropping support.

ICU Planning to Drop Support for Windows XP

A key internationalization library in use by Firefox, ICU, is looking to drop Windows XP support in their next version. The long-form discussion is on dev-platform (you might want to skim the unfortunate acrimony over Firefox for Android (Fennec) present in that thread) but it boils down to: do we continue shipping old software to support Windows XP? For how long? Is this the straw that will finally break WinXP support’s back?

:milan made an excellent point on how the Windows XP support decision is likely to be made:

Dropping the XP support is *completely* not an engineering decision.  It isn’t even a community decision.  It is completely, 100% MoCo driven Firefox product management decision, as long as the numbers of users are where they are.

On the plus side, ICU seems to be amenable to keep Windows XP support for a little longer if we need it… but we really ought to have a firm end-of-life date for the platform if we’re to make that argument in a compelling fashion. At present we don’t have (or at least haven’t communicated) such a date. ICU may just march on without us if we don’t decide on one.

For now I will just keep an eye on the numbers. Expect a post when the Windows XP numbers finally dip below the Linux+OSX as that will be a huge psychological barrier broken.

But don’t expect that post for a few months, at least.
