"new identity" button causes in-progress downloads to be aborted
I recently upgraded my Tor Browser Bundle from the previous stable 2.5.x series to 3.5 rc1.
It seems the behavior of the Torbutton menu "new identity" command has change. Previously, if a download was in progress (using the Firefox download manager), it continued unaffected (using the old circuit, presumably) after "new identity" had been clicked.
In 3.5 rc1, any in-progress downloads are aborted if you click "new identity".
I preferred the old behavior. In the new version, the user is forced to wait until any downloads have completed before switching to a new identity. Users may be tempted to continue using an old identity in situations where this might compromise their anonymity, so as to allow a download to complete.
