I just want to report a problem I'm running into and offer a suggestion. I use Firefox for my AOL web mail. A long term problem with AOL web email is they change ads constantly, almost each time you move your mouse. When one of these ads got hung and didn't load, they often hung Firefox too. That seems to have has been fixed, thankfully. Now when an AOL ad fails to load (probably a hung script) and it effects Firefox, Firefox will pop up a bright yellow banner at the top that reads, "A web page is slowing down your browser. What would you like to do?," offering the option to either "Stop It" or "Wait." Stopping it almost always solves the problem. The problem I want to report is, if you step away for a while and then this happens, and you are not there to click either option, and then your computer goes to sleep (I have a Mac), when you wake it, it seems to have eaten all your RAM. Everything crawls. I've had to wait many minutes just to get enough RAM to try to force quit apps, hoping to kill whichever one is causing the problem. Over time, I've learned when this happens, and my Mac slows to a crawl upon waking it, the source of the problem is almost always Firefox, with a hung up AOL ad. If I can force quit Firefox, I can (albeit slowly) recover normal function. My suggestion: put a preference setting for a timer on these yellow banner "Stop It" or "Wait" alerts. If, say, a few minutes go by with no action on the user's part, automatically "Stop it."
