Hi,
as you might know we have a feature freeze exception to update firefox 3 extensions even though we are close to the release.
However, as we get closer to the release, even extension updates become risky; so please submit your extension packages to the ubuntu mozillateam by the end of this week (Sat 5 Apr).
Please remember to add your extension to https://wiki.ubuntu.com/MozillaTeam/Firefox3Extensions and use the https://wiki.ubuntu.com/MozillaTeam/Firefox3Extensions/Packaging to get an idea about extension packaging best-practices in hardy.
The firefox-extension project in launchpad already has a bunch of bzr branches that you can use as a starting point on how to do this in practice. Remember to file a firefox-extensions bug asking for review and/or sponsorship. Remember to follow up if we ask for improvements or clarifications.
If you need support packaging your extension, ask for help in #ubuntu-mozillateam on freenode. Remember to be patient in case we don’t answer right away as we might be busy or away from keyboard.
Happy packaging!
