Bug 1592752 - [1.0] Conditionally check for storage clearing based on status of LSNG. r=snorp, a=test-only It looks like there is going to be a period of LSNG being disabled on some channels for a while. Making the test conditional on the pref will make it pass in all situations and would allow us to keep the test enabled. It doesn't help with the fact, that on some version we're clearing storage despite the flag not being set, but since it's clearing more, rather than less, it's at least not as critical in terms of privacy.
