The add-on is no longer working in "private browsing" windows. Or am I doing something wrong?

Although it works now with the new version of Firefox, v57, it lacks the possibility of importing or exporting the trace anymore. Can that be fixed please?

I'm only giving three stars this time. Here is why....normally SAML tracer is a 5 star great extension, tremendously useful. BUT with teh new version lacking the ability to import and export.....its completely useless to me now for troubleshooting. I'll revert to an older version but I look forward to the newer update once its fixed. Overall GREAT tool!!
