I used Firefox on the mac, and while I much prefer it to Chrome, I've had no end of stability problems over the last several months, across multiple computers and installs. The problem is that sometimes it will just... freeze up. Spinning ball for the app, completely unresponsive, nothing I can do, sitting at 100% cpu usage. I've let it sit like this for a while, and once or twice it's come up with a "unresponsive script" error, but viewing the same pages in Chrome or Safari never seems to cause an issue and I need to view these pages. My solution so far has been to force quit Firefox when this happens, but losing what I've been working on has been rough now that it's happening 2 or 3 times a day. What I'm wondering is if there's a better way to handle this than destroying it - can I change some setting that says "if it doesn't work for 3 seconds, kill the problem script or whatever don't wait an hour" or to force it to stop whatever it is doing and respond to my commands?
