Here's the bug about making it dependent on a pref: https://bugzilla.mozilla.org/show_bug.cgi?id=1541233 https://bugzilla.mozilla.org/show_bug.cgi?id=1541233 Even just checking for the existence of a file can take a really long time depending on the disk speed and other on going IO.

Checking for the existence of the files could take time since they are in a different directory, but checking for the existence of the chrome directory (which doesn't seem to be used for anything else) should not require disk access since the directory contents are already cached due to accessing other files in that directory. One person mentioned checking for the directory in the bug report but the answer made it sound like they actually checked the speed of testing for the existence of the files in an empty directory rather than checking for the existence of the directory.
