However, a growing number of users are reporting bugs, widening memory leaks, unexpected instability, poor compatibility, and an overall experience that is inferior to that offered by prior versions of the browser. Expanding on these ideas, this list compiles nine reasons why it might be a good idea to stick with 1.5 until the debut of 3.0, skipping the "poorly badged" 2.0 release completely." OK, maybe it's 10 reasons. An anonymous reader writes, "SecurityFocus reports an unpatched highly critical vulnerability in Firefox 2.0. This defect has been known since June 2006 but no patch has yet been made available. The developers claimed to have fixed the problem in 18.104.22.168 according to Secunia, but the problem still exists in 2.0 according to SecurityFocus (and I have witnessed the crash personally). If security is the main reason users should switch to Firefox, how do we explain known vulnerabilities remaining unpatched across major releases?"
Update: 10/30 12:57 GMT by KD : Jesse Ruderman wrote in with this correction. "The article claims that Firefox 2 shipped with a known security hole This is incorrect; the hole is fixed in both Firefox 22.214.171.124 and Firefox 2. The source of the confusion is that the original version of this report demonstrated two crash bugs, one of which was a security hole and the other of which was just a too-much-recursion crash. The security hole has been fixed but we're still trying to figure out the best way to fix the too-much-recursion crash. The report has been updated to clear up the confusion."
