Warning: Shockwave Flash may be busy, or it may have stopped responding.
This issue has been happening for over a year now.
The only way to fix it is to reboot my PC which is frustratingly slow and down right annoying.
It is time Firefox fixed this plugin issue once and for all.
The warnings telling us how to fix the problem are a joke.
What action should I take?
If you get this warning once, you can try to click Continue to give the plugin more time to complete your request. This may not always be successful. If you get this warning a second time you should probably click Stop plugin to make the plugin stop immediately (crash).
click Continue – the plugin continues to hang for anything upwards of 2 minutes and often repeats the pop-up warning two or 2 times.
click Stop – has the same outcome and Continue
Disable this warning
If you don’t want to be warned when a plugin hangs, you can disable this warning by checking the “Don’t ask me again” checkbox. When you do that, Firefox will allow the plugin to hang for up to 45 seconds before it crashes.
It doesn’t work! It continues to hang. After it finally decides to let me proceed, I close the page only to have it all repeated the next time I visit a page that has a Shockwave Flash in it.
Often the page is ok, the Shockwave Flash is a Google ad on the page. How annoying for the publisher.
I estimate it’s been happening to me for over a year.
Gauging by this thread (closed) it is over a year:

I feel the first thing Mozilla needs to do is recognize this is an issue related to one plugin = Shockwave Flash
I feel they need a response specifically for this plugin: Warning: Unresponsive Plugin; Shockwave flash
Mozilla even admits : This thread is now 5 pages and so excessively long.
They go onto say “The comments possibly do not all relate to exactly the same problem.”
They need to stop talking and start listening. (Just unlocking temporarily to comment this page at August 2013 has had about 156 thousand Views. It was opened in April so that is over 10 thousand hits a week)
It is now April 2015 and WE STILL HAVE THE ISSUE!
Adobe Shockwave Flash
UPDATE JUNE 2015
We do love a video, specially one of those cool tech videos like the ones from Apple. so it was great to see one from Firefox.
I watched, listened but not entirely sure what the message was… something about the internet being built by hand.
Then a new web page loaded with this message
Pocket comes to Firefox!
The world’s most popular save-for-later service is now available in Firefox. Sign in with your Firefox Account and you can save articles, videos and more to enjoy anytime, anywhere.
Personally, I’d rather Firefox spent time fixing their desktop browser + unresponsive Flash plugin first!
