For the past few months, my Firefox has tended to hang occasionally or produce "unresponsive script" warnings on a few particular websites. At first I simply avoided those sites, but in the past week or so it's been happening more and more often on more and more sites. After installing the latest Flash update, I've found that almost any time I try to load a page from any site, Firefox displays 1-5 "unresponsive script" warnings, and takes a very long time to acknowledge when I click "Stop Script", so that it will take 5-10 minutes before it can load the page at all. I've found that I do not have this problem as long as either Shockwave Flash or Javascript is disabled, so I suspect it is some interaction between the two, but I would like a more long-term solution!
