I'll write a test for this when my tree is in a better state.

Created attachment 538795 [details] [diff] [review] fix test failure We need to make sure the input pattern is set correctly when we draw the shadow.
http://hg.mozilla.org/integration/mozilla-inbound/rev/a858cef629f0 http://hg.mozilla.org/integration/mozilla-inbound/rev/70c1c696f691 I pushed the test on the assumption it will be OK. If Jeff doesn't like it we can change it later.
Comment on attachment 538795 [details] [diff] [review] fix test failure Probably too late for beta, but might as well draw the attention of release drivers. This is a canvas regression in an edge case, but the fix is very simple.
Comment on attachment 538795 [details] [diff] [review] fix test failure too late for beta. we'll evaluate for 6.
Bug 668742 is about that this issue is still present in the current Firefox 5 release. Can we expect any improvement in a Firefox 5 update or do we need to wait until Firefox 6 is released? Then I know what to tell to people on he support forum that have this problem in Firefox 5. You can see a list of support threads that show this problem in Firefox 5, so we can expect to see a lot more reports about this issue. (cross posting this in bug Bug 668742 as this bug is resolved)

Thanks for confirming that. I was already expecting that (porting code to another branch is not easy), but a confirmation helps to avoid confusion and disappointment.
It's not just porting; there are just no plans to do any Firefox 5 updates before Firefox 6 ships unless a critical issue comes up; if one does an update would contain a fix for just that issue. Once Firefox 6 ships, it becomes the security update to Firefox 5, with automatic updates from 5 to 6.
