Every time I use Firefox browser, I get the error message: "Shockwave Flash is either busy or it may have stopped responding. You can stop the plug in now, or wait to see if the plug in will complete." I also get another one saying that the "Silverlight script is still running" and then I have to wait several minutes before I can view the page. I have uninstalled Silverlight Flash and reinstalled, yet I keep getting either that message or the "script is still running" one ONLY on Firefox. It freezes my web page screen for several minutes. When I use Safari, this never happens. Plug-ins work just fine. It appears that without Silverlight or Shockwave Flash that I cannot watch any videos. I tried YouTube and couldn't open any videos without Silverlight. Please don't suggest resetting Firefox because I've already done that. I still cannot open Yahoo.com home page because I keep getting an error message and I have to go around it by opening news.yahoo.com instead. I have Windows 7 on an Acer laptop. Meanwhile I have reset my default browser to Safari, even though I don't have an Apple computer. It works better than Firefox. Are you planning on fixing the rampant plug-in problem with Firefox?
