Comment 13 for bug 243856

I had the same problem: I was unable to type in Flash on any browser (Firefox, Epiphany, Opera, Midori,) even though my Flash player was the Adobe's latest one (10.0.15.3.) So I solved this problem as follow:

1 In Firefox, [Tools] > [Add-ons] > Disable flash plugin(s), then quit all browser(s)

2 In Synaptic Package Manager, search with "flash" then remove (uninstall) flash entries.

3 Get the latest flash player from Adobe's website.

4 Launch it, then the dialog like "There is the later version in software manager and usually the later the better" and choose "ignore" and carry on installing the flash player which you downloaded from Adobe website.

That's it! I didn't need to reboot the system. Now flash contents works perfectly on my Ubuntu.
