That is part of the patch behind the "security.nocertdb" preference.
I.e. if you set it to "false" your workaround is still supposed to work.
That said it might be smarter to bind that preference to the private
browsing mode (as the "Permanently store this exception"-checkbox
already is) than messing with the checkbox itself. Do you mind opening a
ticket at https://trac.torproject.org?

There is no recommended way :) but as I said above switching
"security.nocertdb" to "false" should help.
