Toggling permissions.memory_only causes crash of Tor Browser
While investigating #9531 (moved) I run into an other reason for crashing when hitting New Identity:
WARNING: NS_ENSURE_TRUE(asyncCloseWasCalled) failed: file /home/firefox/tor-browser/storage/src/mozStorageConnection.cpp, line 943
Assertion failure: !mAsyncExecutionThread, at /home/firefox/tor-browser/storage/src/mozStorageConnection.cpp:415
Program ./Browser/firefox (pid = 30485) received signal 11.
Commenting out the code toggling "permissions.memory_only" seems to help.
