1244806 - browser.download.dir and related options should NOT be synchronized to other machines

Status: RESOLVED WORKSFORME

(Firefox :: Sync, defect)

Description

[fireattack [:fireattack]]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160127070712

Steps to reproduce:

Currently, the settings of browser.download.dir, browser.open.lastDir, browser.download.lastDir and etc will be synchronized.

I think it makes no sense because user may have totally different folder structures on different machines. 

For example, I set the default download directory to Desktop for both o my computers. However, my two computers has different user name. Surprisingly it won't cause problem when I download a file, but it will cause problem when i am using "Save image as.." feature, because it will select "browser.download.lastDir" which is a folder I don't have access on computer B (if it's sync'd from computer A).

These prefs aren't synced by default - the list of default preferences synced can be found at https://dxr.mozilla.org/mozilla-central/source/browser/app/profile/firefox.js#1243 - but note that because preferences store the preferences to sync (meta!), it's possible to add your own list of preferences to Sync - is it possible you (or an addon?) added these prefs manually? What does about:config say about the preference "services.sync.prefs.sync.browser.download.dir"?

Thanks for the info. I don't know if this is a recent change but I indeed cannot reproduce this bug any more. Closing.
