firefox on ppc64 (a big-endian platform) is crashing on startup in mozilla::layers::CreateTexturedEffect aFormat=mozilla::gfx::SurfaceFormat::X8R8G8B8 which is not covered by the case statement.

user_pref("layers.use-image-offscreen-surfaces", true); triggers this bug, things work setting it to false

does just adding it to the list fix things?

Comment on attachment 8713948 [details] [diff] [review] patch? Review of attachment 8713948 [details] [diff] [review]: ----------------------------------------------------------------- I need to add both + case gfx::SurfaceFormat::X8R8G8B8: + case gfx::SurfaceFormat::A8R8G8B8: To stop the crashes but that just results in pages that don't render properly (I'll upload a screenshot)

Screenshot of what I see when I add the two surfaceformat values to the case statement.
