Environment: Device: Asus Transformer Pad (Android 4.2.1); Build: Firefox 39 Beta 4 build 2; Steps to reproduce: 1. Go to Settings -> Privacy; 2. Disable Cookies; 3. Restart fennec. 1. Go back to Settings -> Privacy; Expected result: After restart the Cookies are disabled. Actual result: After restart the Cookies are still enabled. Notes: Attached are the logs from logcat; Looks like if I wait like 30 second after I close Fennec and then open it again the bug will not reproduce. Can not reproduce it at all on Aurora or Nightly.

[Tracking Requested - why for this release]: regression Ni to Margaret for an assignee

Sounds like we need to flush gecko preferences to disk after they change. liuche, can you look at this?

Since bug 1118818 landed in 40 and fixes that issue, it looks like we just need to uplift that to 39. We're nearing the end of the cycle though, so rnewman, can you think of any reason we shouldn't request uplift?

If you can verify that this doesn't repro in 40+, then uplifting that fix is safe IMO. Run with it!

Hm, I tried this on fresh Betas from the Play Store (6/12) installed on the following devices, and could not repro this. Flaviu, can you repro this on a device that matches one of the ones that I tried? Nexus 7 (5.0.1) Nexus 9 (5.0.1) Asus Transformer TF101 (4.0.3) Nexus 4 (4.4.4)

My STR: - Open Settings > Privacy > Cookies - Switch from "Enabled" to "Disabled" - Swipe close from recent apps - Re-open, go to Settings > Privacy > Cookies

It may be specific to device or android version.

Flaviu, does this build fix the issue on the affected devices? http://people.mozilla.org/~liuche/bug-1173388/flush-beta.apk This is a build of the patch from bug 1118818 on top of a pull from beta this morning.

I can not reproduce the issue using this build.

The patch from bug 1118818 is landed in beta, and that should fix this, so I'm duping this.

Marking this as fixed based on bug 1118818.
