819571 - some urls resulting from add-on installation in PB mode show in about:cache

Status: RESOLVED INVALID

(Firefox :: Private Browsing, defect)

Description

[juan becerra [:juanb]]

Using latest birch nightly, if I install an add-on in a PB window and restart there will be some AMO urls left in about:cache?device=disk. Those seem to be the URLs that you hit when you click the "install" button in the addon page. It doesn't seem serious, but I didn't expect to see anything related to AMO there.

Steps:
1. Open a PB window using command-shift-p
2. Go to addons.mozilla.org
3. Look for "timer fire"
4. Install the add-on and restart
5. Go to about:cache and click on "list cached entries" under Disk Cache Device
6. Look for "addon"

Expected: No urls containing "addon"

Actual: Some urls with addos.mozilla.org

Can you please post the URLs that you're seeing here?  Thanks!

My suspicion is that this is fine, since you're making a persistent change to the browser and these are related to that change.

Marking as unconfirmed until we have more information here.

This is fine, the add-on installation itself is persisted, and we do not want to prevent people from installing add-ons in private windows.
