Starting with Celena Linux Mint will maintain its own Firefox package. Based on the Ubuntu package it will include Linux Mint’s own modifications and prevent Ubuntu rebranding when Firefox gets a security upgrade.
For the user this means:
– The default Firefox homepage won’t be impacted when Firefox gets upgraded any more.
– There might be a slight delay between the moment when Ubuntu releases an upgrade for Firefox and the moment when Linux Mint does the same.
For this to work the Mint package will use a different versionning scheme, removing dots between minor numbers. For instance Firefox 18.104.22.168-ubuntuX in Ubuntu will correspond to Firefox 2006-mintX in Linux Mint.
