649162 - Firefox sync preferences lost if saved password data/history is cleared

Status: RESOLVED DUPLICATE of bug 553400

(Firefox :: Sync, defect)

Description

[gene.730+bugzilla]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0

Just noticed that if I use permanent private browsing mode, or if I use custom settings for history that include Clear History when Firefox Closes > Data: Saved Passwords, this also clears any pre-configured sync settings in Options > Sync.

Always able to replicate

Reproducible: Always

Steps to Reproduce:
1. Firefox 4 > Options > Sync > Complete a sync relationship/configuration (right up to the point where the URL loads to notes that sync is now configured)
2. Firefox 4 > Options > Privacy > Tick "Permanent private browsing" or use custom settings for history that includes Clear History when Firefox Closes > Data: Saved Passwords
3. Exit Firefox completely (Firefox > Exit)
4. Start Firefox
Actual Results:  
Now Options > Sync is "unconfigured" - any subsequent changes will not sync. Choosing Firefox > Synchronise now results in a prompt to setup sync. 

Expected Results:  
Clearing saved passwords for websites does not affect sync settings/sync credentials

Workaround is to *not* tick Clear History when Firefox Closes > Data: Saved Passwords. This is required even if Security > Remember passwords for sites is unticked

Or to rephrase - to me the "Clear History when Firefox Closes > Data: Saved
Passwords" area means "Saved passwords for websites". I don't expect it to mean sync settings/credentials.
