Comment 9 for bug 886302

Using Flash 10 instead of Flash 11 will break the (probably now hundreds, if not thousands) of websites that only work with Flash 11, either because they use features only present in major version 11, or because they trigger bugs that were fixed in major version 11 (or in some incremental release after that). Using Flash 10 is therefore not a generally good solution to the problem of this one website not working. The goal of making Flash work better for users in general would not be served significantly by fixing this bug, and the goal of making Flash work better for users in your specific situation, while it would be served by fixing this, would not be served particularly well.

That is not to say that this bug should not be fixed. It might well be the case that there is significant benefit to giving users the ability and option to choose Flash 10 (packaged for Ubuntu) as well as Flash 11 (packaged for Ubuntu). I am not convinced that this is the case, but I hope this post should not be taken as an argument against it.

Either the website should be fixed, or Flash 11 should be fixed (depending on which contains the bug). If the website is fixed, then no one needs to update anything. If Flash 11 is fixed, the update will presumably be available to all users of all supported Ubuntu releases, including Ubuntu 12.04 LTS once it's out (whether the fix happens before or after its release). This is because Adobe Flash is proprietary and there is no way for Ubuntu developers to backport just fixes for security vulnerabilities and serious security/stability bugs, creating Ubuntu-specific versions (https://wiki.ubuntu.com/StableReleaseUpdates). Since this cannot be done, updates to Flash in Ubuntu get new features (and new bugs) as well as fixes for serious bugs.

Have you actually replaced Flash 11 on your system with Flash 10 to see if that actually fixes the problem on the BBC website?

"Also, am thinking of other users as well. And when or if Adobe manage
to get Stage Video/3D/whatever sorted - would prefer to just accept the
update through Update Manager..."

Are you saying you think Adobe will release additional updates for Flash 10 providing major functionality changes?
