Firefox issues are way easier to track down as regressions by eliminating differences between working and non-working version. The first candidate is always the fragile user environment, so you need to start from a clean slate by populating a jail with X11 pass-through and trying to reproduce there. After that you can start bisecting which should determine if the issue is port-specific or due to upstream update. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQF8BAEBCgBmBQJW5a1gXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXREQjQ0MzY3NEM3RDIzNTc4NkUxNDkyQ0VF NEM3Nzg4MzQ3OURCRERCAAoJEOTHeINHnb3b8JEH+QFaS4yVDU1PCj1uVOW3nQ+f 1fb9xaLfaIC7xbhMeevnPnz0aTZn2ihMVCRpZ7bWmPpaxrM8skgDNvAT70Vx+K3s Mu4ezT8ioz6lz0m6Kf7GoJEDrrcbuaR4l0jEGoeK0mZgDQzurdV5tS5dF4MxSiLc WcGJx0ofL0xeTTbXDEe9d/uD3Ucmy1TkgXA9RqkeQo385ro89uI8+UN47bH3DDou oFUyC9PGGV5k5RSgHWpwKZ0CpEvaffu2+eftbu/vubJUC8aTV7fnReJ6g7kGRgon 695Q+Z+WZYiV6Pl9FrYS+lFy0t1dgS9E4ImSt3AkRVRBSh/Roa9aIeq7KD2cdao= =ORie -----END PGP SIGNATURE----- --=-=-=--
