Firefox to get faster, less intrusive updates
Mozilla engineer Ehsan Akhgari has been toiling away at the improved delivery system for Firefox, and it’s now ready for testing. Here’s how the new Firefox update process works: when an update is detected, Firefox launches the background updater and installs the new files in a separate directory. When Firefox is restarted, it’s a simple move and replace operation that occurs — and that’s much faster than actually performing the update installation during start-up.
Akhgari has set up a new temporary Firefox channel called Ash for those who are willing to help out with initial testing before the new updater is pushed to the usual Firefox channels. If you’d like to get involved, download and install the Fifrefox Ash build. Akhgari will push several updates per day so that the new system can be thoroughly tested.
