I’m viewing all this on Firefox/Mac 10.4.9 (in other words, I’m not trying anything fancy here). When I first began having the reversed-slash issue in Firefox (and IE Windows), I still was at least able to navigate through my admin panel. Now it’s giving me errors and redirects.

Admittedly your fix might not be the cause of the current problem. I’ll reinstall and see what happens. Your fix certainly was successful with the original problem. Thanks again.
