it is my novice understanding that clearing Data or removing Sync account will not always consistently wipe your preferences or clear all your data. Things like timestamps stored in prefs may still linger around on your phone. The only way to ensure a clean entry is to completely delete your Fennec App. We can't ask users to realistically do that, so this bug is to track how to effectively fix the Sync Adapters so clearing data/removing Account should guarantee a clean profile. Do correct me if i'm wrong. Per irc: tchung: rnewman|working: so explain to me again why i need to completely uninstall fennec if i want to start a clean profile? (and clearing data isn't enough?) [01:51am] rnewman|working: tchung: timestamps [01:51am] rnewman|working: they're stored in prefs [01:51am] rnewman|working: theoretically clearing data should clear those [01:51am] rnewman|working: and yet I've seen instances where it has not [01:51am] rnewman|working: which is really confusing [02:02am] tchung: rnewman|working: so is the intermittent cleanup in prefs you describe something we have a bug on file for yet? we certainly can't ask all users to uninstall their app if they want to clean up their sync. [02:05am] rnewman|working: it's part of resetting [02:06am] rnewman|working: we don't implement any of the wipe, reset, timestamp clearing etc. logic [02:06am] rnewman|working: I put in a hack to wipe prefs when you set up an account, but it doesn't work, and I don't know why clearing data doesn't either -- perhaps if sync is still in memory it writes them out again? [02:06am] rnewman|working: SyncAdapters are funny things

We can do this on add or on removal, or both.
