Yes... me too....
on mobile devices as far as I know it cannot even be enabled. In this case it will be possible, but it is usually the case that once something is set by default, that is what 99% of users will use. Very few people will actually know how to enable it, go to the settings and turn it on. Not to mention the fact that even users like me, who know very well how to turn it on, might not do so (including me) because Google had a very good reason for doing this...
I hope this will not cause any major problems though because all webmasters who use Flash should be aware of the problems associated with this technology and this is something that everyone knew was coming sooner or later.
I knew this too and so I never included any plugin, block or anything that would use Flash in my template.
Two things that I can think of that will cause problems to many people on this forum are Weather Display Live and YoWindow. This is also why I said I will not make a block for YoWindow.
Flash is nice, or rather I should say was nice, it allowed to do things otherwise impossible, but we all know how vulnerable and unstable it was, but given there was no alternative, it was used very readily.
However these days, HTML5 in combination with CSS3 can do even more so there is no point in using Flash any more.
