Firefox is much more secure than I.E. Patches are released almost immediately rather than the following Tuesday  (if Microsoft deems the issue critical). If you have a problem with a version of Firefox, make sure you aren't using the nightly builds. Those are test builds (though I've never had trouble with any).

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
