In all the edits/revisions of my earlier “Fun and Games with Major Updates” blogpost, somehow I dropped the following by accident:
Disclaimer: for the purposes of simplicity, I intentionally avoided mentioning two edge cases:
- We never make major update offers to a user if they are running on an o.s. that is supported in FF2, but *not* supported in FF3. After all, if the user accepted that major update offer, they would be broken as soon as the upgrade completed! A user on an older unsupported o.s. who does “check for updates” would simply see “no updates available”… which is true for that o.s.! As you would expect, if that FF2 user upgrades their o.s. to something that *is* supported in FF3, then when the user next does “check for updates”, they will see the major update. The numbers are small enough anyway as to not make a significant difference to the discussion, and it would have really complicated the diagrams even further!
- Firefox installations on locked-down machines never check for updates. This is true for both minor updates and major updates. Typically these are machines that are locked down by IT dept, or where the user does not have Admin privileges to install new software updates.Â As we never hear from these users ever, we have no idea how many users this impacts, and they are not included in any of our user counts.
