I love Firefox, and it is hard for me to imagine changing browsers. But I have had nothing but crash after crash since updating to version 18.104.22.168 a couple of days ago. Among the many web sites that consistently crash Firefox, but work in IE, are the Time Warner, Houston page, Feedburner and Webshots (which is a great application for hosting images like the one below).
UPDATE: Actually Webshots is great for losing photos when it died. I lost this one and tons more.
I expect I am not the only person having these problems.
