To generate the XPI, do the following: hg clone https://hg.mozilla.org/releases/firefox-hotfixes cd firefox-hotfixes HOTFIX=v20160128.01 make package Then we need to sign the xpi generated at build/hotfix-v20160128.01.xpi Please deploy to addons-dev.allizom.org for QA

Signed hotfix is attached. I'm having trouble uploading it to the staging server, at the moment.

Verification steps: A) Verify that you can reproduce the bug without the hotfix using these STR: WARNING: This will delete all logins without the fix/hotfix. 1) Run a version prior to Fx44 with the prefs: * privacy.clearOnShutdown.passwords = True (add it as new in versions after 42) * privacy.sanitize.sanitizeOnShutdown = false * privacy.sanitize.migrateClearSavedPwdsOnExit = false or unspecified 2) Add some saved passwords (they will be deleted) 3) Upgrade to Fx44 Expected result: All logins are still present in Preferences > Security > Saved Logins… and the "Remember Logins" checkbox is still checked. Actual result: All logins are deleted. The "Remember Logins" checkbox is unchecked. B) Perform the steps at https://wiki.mozilla.org/Add-ons/Hotfix#Testing_the_hotfix_locally C) Perform the steps at https://wiki.mozilla.org/Add-ons/Hotfix#Testing_the_hotfix_on_the_staging_server D) With the hotfix installed in pre-44, verify that you get the "Expected result" in the STR from (A) upon upgrading to Fx44 instead of the "Actual result".

Anthony, could you please test the hotfix once it's on the staging server? Kris, could you please let us know when hotfix is on the staged server? You mentioned having difficulty upload it in a previous comment.

To clarify, for (D), perform STR steps 1-2, install the hotfix then do step 3.

I confirm that the local hotfix seems to work as expected. A: 1) Install Firefox 43 and started with a new profile 2) Set prefs in comment 3 3) Saved some website passwords 4) Updated to Fx44 > Passwords removed, 'Remember logins for sites' unchecked B: 1) Install Firefox 43 and started with a new profile 2) Set prefs in comment 3 3) Saved some website passwords 4) Install the hotfix .xpi 5) Update to Fx44 > Passwords remain, 'Remember logins for sites' checked

The hotfix is now live on the staging servers.

Re-assigning the bug to amo team for final deployment now that QA sign off is done.

The hotfix has been deployed to production.
