got a similar problem. I was with 6 tabs open, two of them using javascript (gmail and yahoo! finance page), a google search for "graph visualization java" the main page of jgraph open, another java graph visualization page and the free download page of jgraph, when I clicked on the binary package to download, CPU went high (beat 100%, then back to 70%) and firefox crashed.
I'm also using Edgy Eft always up-to-date, firefox should be the latest released package. ** Attachment added: "crash file captured by ubuntu" http://librarian.launchpad.net/5563880/_usr_lib_firefox_firefox-bin.1000.crash -- when firefox is working, cpu start to work heavy and at the end firefox crash. It's not the first time and sometimes the crash became a system crash https://launchpad.net/bugs/76523 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
